PERIODIC PERFORMANCE TESTING

FOR POWER PLANTS & POWER GENERATION EQUIPMENT

Evaluate periodically the performance parameters of interest to comply with LTSA contractual evaluations and the requirements from the dispatch. Compliance with the performance testing protocols from ASME, ISO, DIN and other standardization entities.

INDEPENDENT & IMPARTIAL

Periodic performance testing of power plants around the world to determine the technical parameters, performance changes over time and plant or equipment performance degradation.

The performance testing protocols from standardization such as ASME, DIN and ISO will be followed and the test uncertainty will be within the expected values specified in ASME PTC 19.1 for the type of power plant, fuel and plant configuration.

LTSA CONTRACTS AND DISPATCH REQUIREMENTS

LTSA contracts that guarantee performance over several years require periodically evaluation of their performance guarantees and degradation of the plant or equipment. In the same manner, dispatch company/centers require to update the technical parameters of power plants to optimize their dispatch decisions. Some of these parameters are the following, additional parameters can be evaluated based on the requirements of the contract or technical specifications.

Power Plant Electrical Output

Baseload Output
Partial Load
Minimum & Maximum Load

Power Plant Heat Rate

Power Plant Heat Rate and Heat Consumption at different load levels.

Performance Degradation

Understand the level of degradation in your power plant and main power generation equipment.

Start-Up and Shut-Down Costs

We can help you to determine the costs, time and start-up/shut-down parameters in old, warm and hot conditions.

POWER PLANT PERFORMANCE DEGRADATION

Back to Top

Power plant performance degradation is part of many LTSA contracts as well is important for the profitability of power plants. There are two types of power plant degradation.

Non-Recoverable Power Plant Performance Degradation

Non-recoverable power plant performance degradation refers to the degradation that occurs in a power plant due to the wear of the equipment and parts. This type of power plant degradation is hard to overcome without hardware changes to the equipment and is very unlikely to be fully recovered over the life of a power plant without upgrading the main equipment. This is the degradation that will be determined in a periodic evaluation of LTSA contracts.

Recoverable Power Plant Performance Degradation

The recoverable power plant performance degradation in a power plant is related typically with the daily operations and ware of small components that decrease the performance of the equipment and the overall plant. For example the online water wash in gas turbines or soot blowing in a coal-fired boiler can recover some of the lost performance. During a power plant periodic performance test, the goal is to minimize the amount of recoverable power plant performance degradation accumulated at the time of testing.

BEFORE AND AFTER TESTING

Back to Top

A before and after performance test is conducted, as its name refers, when we have an event in the plant that can have a large impact in the performance of the total power plant or its main components.

For example before and after a major inspection, a power plant upgrade or changes in the fuel specifications. Any modification to the plant can impact its performance and testing the plant will give you the insight you need to quantitatively measure this.

Another important aspect of a before and after testing is that it typically requires less amount of instrumentation than a full acceptance performance test as a lot of the measurements will be done using station instrumentation. ASME PTC 19.1 Performance Test Code – Test Uncertainty the systematic uncertainty of the comparative results is cancelled if the same instrumentation is used for the before and after test.
