Cogeneration Plants

TGPS conducts cogeneration performance testing of power plants around the world. Our company has a global team of performance engineers and technicians that are ready to provide you with un-biased cogeneration efficiency analysis. Possible you are interested in your combined cycle heat rate or in the efficiency of your individual equipment. Our team is ready to support the performance needs of your plant.

Cogeneration Performance

Our company evaluates the cogeneration efficiency of different suppliers such as GE, Siemens, Alstom, Mitsubishi, Ansaldo among others. The cogeneration heat rate and cogeneration efficiency are among the parameters of major interests. However, from a total power plant performance analysis, TGPS also analyze the individual equipment efficiency that could impact your cogeneration heat rate and power output.

The plant configuration can vary a lot depending of the application. Depending on the balance between electricity demand and heat consumption (air, steam, water) the cogeneration efficiency varies. Therefore, there is the need prior to conducting any performance test, there should be a cogeneration performance test procedure that describes in detail how to evaluate the cogeneration power output and cogeneration efficiency.

We hold a large inventory of testing equipment to conduct high-precision combined cycle performance test around the world. For example, this is particularly useful when there is the need to minimize your combined cycle heat rate test uncertainty.

Several factors can alter the cogeneration efficiency over time. Operational modes, equipment degradation, load cycling, etc.

TGPS helps you to identify the areas of opportunity to improve you cogeneration efficiency.

Compliance with the applicable international performance test codes such as:

Cogeneration Performance Test Procedure

For a cogeneration performance test, there are certain specific items to place special attention during the creation and revision of the site-specific performance test procedure. For example some of the key areas that need to be very detailed are.

  • Cogeneration cycle Isolation (thermal and electrical isolation)
  • Test Boundaries Definition
  • Performance Test Guarantees
  • Performance Testing Instrumentation (temporary & permanent)
  • Calculation of the final cogeneration performance test results.

TGPS has a diverse range of experience in cogeneration plants. and we follow in general the applicable testing codes such as ASME PTC 46, ASME PTC 22, ASME PTC 6 among otheres.

Acceptance Test vs Diagnostic Test

Depending on the objective of cogeneration performance test, certain parameters are more critical than others. Only an experienced power plant performance engineer can guide the process through an efficient plan of action. For a contractual performance test topics such as test uncertainty, performance guarantees are more relevant. In a diagnostic test, not only these parameters are important, but also looking to historical trends, power plant upgrades, operation modes, load cycling, among others. Our team uses the latest tools to diagnostic the cogeneration performance in an accurate and practical way. Results that can impact directly cogeneration efficiency.

 

High-Precision Performance Testing Instrumentation

The need to ensure that a cogeneration performance test results have an acceptable level of uncertainty, requires in most instances the use of temporary instrumentation to be used during the performance test. TGPS holds large inventories of testing instrumernation around the world to satify very detailed testing programs around the wold.

Why is Power Plant Efficiency Important?

Power Plant Efficiency is directly correlated to the business sustainability in terms of financial performance and long-term feasibility.
