Surviving Hurricane Harvey

September 14, 2017DavidGeneralComments Off on Surviving Hurricane Harvey

Thank you to all the wonderful customers and friends we have for worrying about us over here in Houston.  For sure it was something tragic for the city of Houston and surrounding areas.  Our office is located on the west side of Houston right between the two large reservoirs where all the flooding happened.  However, we escaped the water fortunately with only minor wall and floor damage in one office.

I can‘t say the same of some of our employees who had to be rescued from their homes by boat.  To the left is one of the photos of a house on the same street as our Engineering Manager.  You can see the house is not only flooded, but they forgot to turn off the main breaker before evacuating and the result is that second floor burned.

 

 

 

 

 

Take a look at the rainfall totals for previous tropical systems and you can see that our area received a lot of water!

Paving the Way with Predix

July 28, 2016GinaGeneralComments Off on Paving the Way with Predix

2016-07-27 09.23.06

Real Time Power attended GE’s Predix Transform 2016 this week in Las Vegas. Predix is GE’s newest platform that connects GE and Non-GE machines inside a secure cloud industrial infrastructure.

Having the capability to compute analytics and make real-time decisions within the application is one of the main factors that interested our engineers at Real Time Power to attend this conference. The industrial internet machine revolution is upon us and by keeping abreast of all the latest forms of technology and how we can best adapt them to our own artificial intelligence is important in regards to staying relevant in a field that is always changing.

Being able to use Predix to shorten the creation and utility of essential apps is a great feature. This helps our end users by minimizing down time to make updates and changes to our application modules while avoiding normal delays in a software integration environment. We are currently evaluating our existing apps which can be modified to run on GE’s cloud infrastructure

After attending the conference, Real Time Power’s key takeaways for the utilities sector are:

–         We’re interested in the single platform to integrate the various plant components in a power plant.

–         We think our deep performance knowledge of non-GE OEM gas turbines will make the platform better.

–         We think our gas turbine AirSonic ™ air mass flow measurement system will be a key sensor that can be used for better diagnostics and analytics.

–         The platform is still quite young and needs more adopters to identify improvements.

–         We are unsure that if a customer already has analytics software, enterprise dashboards, etc, how will putting it in Predix give sufficient ROI?

–         GE is 100% committed to be the leader in this area and is putting over $1B dollars of investment in this platform for next year.

–         Support and maintenance of the apps/data will still be manual in a lot cases just due to the nature that more data and analytics means more false positives and more data mining work.  We think 3rd party vendors such as Real Time Power will be able to fulfill a niche here.

–         For an inaugural conference, Predix Transform was 1st class and felt like it had been ongoing for years.

What can you see from Real Time Power while using Predix? We are currently evaluating an application that will facilitate the ease of monitoring your power plant and making real time changes to your operation schedule. Real Time Power is committed to finding ways to optimize your profits and simplify your power plant’s operational processes.

Simplifying Thermal Energy Storage while Optimizing Profits

July 22, 2016GinaGeneralComments Off on Simplifying Thermal Energy Storage while Optimizing Profits

Thermal-Energy-Storage-Fig-1

Thermal Energy Storage (TES) systems are key players in increasing gas-turbine-powered plants profitability and improving the reliability of operation on the distribution grid. By using a TES system, plants can exploit daily pricing patterns to chill water in off-peak hours and then provide turbine inlet-air cooling in peak demand periods to boost output and improve heat rate.

Any power plant that utilizes a TES system will be able to quantify the monetary benefits immediately. However, California’s AB 2514 Storage policy is in action and is requiring the California Public Utilities Commission to create a commercially viable energy storage system for the state’s investor-owned utilities (IOUS) and to be in full effect by 2020. Although, this is the first law nationwide that is making it mandatory to have an energy storage system in effect, we may see more plans like this showing up in other states as well.

TES optimization is performed by maximizing the cash flow derived from chilled-water resources while respecting the plants’ physical and operational constraints. Real Time Power’s adaptive and intelligent TES Advisor (TESA) Solution provides an easy and simplified operation schedule for day-ahead and real time bids which takes away the guess work of dispatchers and plant operators.

With TESA, operators and dispatchers are shown the appropriate gas turbine inlet temperature set point as well as the recommended chilled water tank operation mode and are sent directly to the operators’ DCS.

TESA is the missing link to your power plant’s success with thermal energy storage and greatly simplifies a very complex system.

7th EVI-GTI Gas Turbine Instrumentation Conference

November 4, 2015DavidGeneralComments Off on 7th EVI-GTI Gas Turbine Instrumentation Conference

Our very own Ray Boucher presented a paper about our Real Time Power’s accurate ultrasonic Air Mass Flow Measurement system for gas turbines along with the challenged and new develops planned.  The conference was held in London November 3-5, 2015.

EVI-GTI Gas Turbine Conference brings together the global gas turbine engine test instrumentation and development community in 2015 to showcase their latest research and results to an international community of like-minded specialists.

The air mass flow rate into the compressor of a gas turbine is a key parameter for determining and predicting the performance of combined cycle gas turbine (CCGT) power generation units. An accurate measurement of air flow rate can be used to improve the prediction of the gas turbine generator power output at the point when the exhaust gas temperature constraint is reached, and the subsequent calculation of thermal energy flow rate into the heat recovery steam generator (HRSG) improves the prediction of the steam turbine generator power output.

The direct measurement of air mass flow rate is difficult because of the complex geometry of the air intake duct, and also because of the high levels of noise, vibration and air turbulence that are present. The paper presented the experiences gained from deploying a direct ultrasonic measurement of air speed in the intake duct, which is used in combination with static pressure measurements and the results of computational fluid dynamics (CFD) simulations to produce a real-time measurement of air mass flow rate. The challenges, accuracy and benefits of ultrasonic air mass flow rate measurement was discussed using experiences gained over the last six years from 28+ field installations covering five different types of large (> 150 MW) industrial gas turbines.

Improve plant profitability by optimizing thermal energy storage

Improve plant profitability by optimizing thermal energy storage

Thermal energy storage (TES) systems increase profitability of gas-turbine-powered generating plants by exploiting daily pricing patterns to chill water in off-peak hours and then provide turbine inlet-air cooling in peak demand periods to boost output and improve heat rate.

However, TES systems often are operated using default running schedules based on vendor design calculations, which do not account for the actual prices of electricity and natural gas, or weather conditions, or the thermodynamic state of the plant. The high variability in external and internal conditions during plant operation implies that a fixed operating policy is sub-optimal in real-world situations.

This means further significant benefits—perhaps $1500 to $3000 per day for 500-750-MW combined cycles—may be available by optimizing TES operation. Real Time Power Inc (RTP) shared with attendees at the recent Combined Cycle Users Group annual meeting (Orlando, Aug 24-27, 2015) the company’s automated software solution for computing the optimal TES run schedule for both day-ahead and real-time markets.

RTP’s David Davis explained the application and how data from both the powerplant and energy trading floor are used in state-of-the-art optimization techniques to maximize cash flow within a given time period.

A typical TES system produces chilled water which can be stored in a large well-insulated tank or sent directly to cooling coils in the gas-turbine air inlet house (Fig 1). Inlet air also can be cooled using chilled water from the tank, a preferred option for peak demand hours to reduce parasitic power consumption.

Thermal Energy Storage Fig 1

The chilled and unchilled water are stored in the same tank; there is little mixing between the two layers. The thermocline level is defined as the height in the tank where there is greatest temperature difference between the warm water above and the cool water below.

TES optimization is performed by maximizing the cash flow derived from the chilled-water resource while respecting all of the physical and operational constraints. Silvia Magrelli, the R&D software engineer at RTP who led development of the application said the optimal schedule requires the “solution of a constrained multivariable nonlinear objective function, and with the selection of the appropriate solver algorithm, the machine-generated answer will provide significant additional revenue gain over and above the default schedule.”

The optimizer is layered on high-accuracy adaptive plant models which allow it to calculate key powerplant operational parameters for the forecasted weather conditions, and then also to predict precisely the incremental power and heat-rate benefit of inlet-air cooling, as well as the auxiliary load of the chiller units.

The final pieces of the jigsaw puzzle are forecasts of electricity and natural-gas prices, which enable decisions regarding GT run schedule. The outcome assures sufficient chilled water is available to meet the forecasted needs of the day-ahead market. Plus, in real-time trading it allows sudden changes in market and/or weather conditions to be assimilated immediately and the best use of the TES re-computed for the remainder of the trading day.

One important benefit of the optimizer, Team RTP stressed: It greatly improves the accuracy of day-ahead load forecasts because it always plans to return the TES tank to a specified state at the end of each day. Thus, at the start of each trading day, the thermocline level is the expected value, and the forecasted load and heat rate can be achieved if the TES is operated according to the optimal schedule.

By contrast, with a default schedule, the end-of-day thermocline level is uncontrolled and will affect megawatt and heat-rate numbers for the following day. Finally, when plant equipment constraints are reached—such as maximum chilled-water flow rate through the cooling coil—the system will plan the day-ahead and real-time schedules based on best achievable performance.

Thermal Energy Storage Fig 2

Real Time Power has tested the application against five years of real price and weather data using actual plant thermodynamic models. Figs 2-4 presents the results of this retrospective comparison for a 3 × 1 combined cycle in the South with a 5.75-million-gal storage tank. The optimizer consistently outperforms the default schedule, and over the five-year period investigated, would have produced a $6.6-million benefit. The saving results from differences between the actual electricity price on the day and price curve used in designing the TES and in compiling the default schedule.

Thermal Energy Storage Fig 3

Installation of the RTP solution involves a server which connects to both the plant DCS and the energy trading desk. Control-room operators have the opportunity to set independent variable values and constraints—gas-turbine availability, for example. The system typically is accessed daily by the trader to produce the day-ahead declaration, and subsequently, as required during the current day, to make changes reflecting the real-time market.

Thermal Energy Storage Fig 4

The optimal solution for a particular running configuration is computed in less than one second, making the system very responsive to changes in market and weather conditions.

We had a great turnout at the 7FA show and thanks to all the customers who stopped by. Many customers were interested in gas turbine reliability and the advantage of measuring air mass flow rate in addition to the typical OEM unit instrumentation to give accurate predictive performance of their engine. Water wash optimization was a hot topic and we were able to show them how they can see online and offline water wash performance results in real time. Additionally, some merchant energy customers were impressed by our ability to accurately predict day ahead high and low plant loads as well by using real time unit performance in continuously adaptive models. Most of all, they liked the fact that we are able to work across their fleet of heavy duty gas turbines, regardless of OEM, thus giving them an independent verification of each units’ reliability and performance!

The top question of the night was “Why doesn’t GE do that?” Remember, at the end of the day, the OEM makes money off selling you parts, outage services, CSA’s, and LTSA’s. We do need these large OEM’s around to bring in the best gas turbine technology available. However, you can’t be the best at everything. At Real Time Power, our total focus is your units’ longevity and optimization. We know you are in the business to make money and that only happens if you have the most optimized and reliable unit possible!
