Gas Turbine Controls
Popular for the production of most electrical power are steam turbines. However, for some applications such as peaking generators, cogeneration, combined cycle, pipeline and process compressors steam turbines may not solve the overhaul issues of power. For these applications the addition of combustion turbines are required.
In a gas turbine, fuel is mixed with air and ignited in the combustor. These hot expanding gases are forced through the hot section ofthe turbine, powering their rotation. Energy is captured in the form of shaft rotating power, compressed air, or both.
In order for the turbine to reach maximum efficiency and longevity, precise gas turbine controls are needed. When choosing gas turbine controls, several factors should be kept in mind. We will examine five.
First, the readability of the control is vital. The most important information must be clear and prominent on the instrument with the meaning of the reading clear.
Second, the accuracy of the controller is paramount. Faulty information could be fatal, not just to the turbine, but to those operating it. In fact, checks and double checks of some data are needed.
Third, startup control is important since the startup of a turbine cannot be too fast or too slow. When startup is not handled properly, much waste and certain risk may result. Fourth, alarms must be available that allow operators to monitor turbine activities and to respond to conditions that could indicate a problem.
Fifth, preventive maintenance is important. Some turbines are operating beyond their expected lifespan and this makes preventive maintenance even more important. One example would be fast or slow temperature changes that may indicate a nozzle problem. Checks on key parts of the turbine should be made as standard procedure after a given length of operation. Good controls will keep track of this and notify the operator when a maintenance check is needed.
All of these factors are important and no gas turbine control system is complete without all of these. As an example, one gas turbine control system displays the following data: Indication of when turbine acceleration is passing through vibration criticality; Text prompts of critical milestone check with time remaining during startup; Indication of “startup probability” prior to startup; Elapsed startup time; display of selected group of system; parameters for all exhaust temperatures along with temperature spread presented in a single graphic active control/mode type.
When a company is considering purchasing a gas turbine control system, it is extremely important that reliability and a good reputation are paramount. The future life of the turbine and success of the company are more important than a few dollars saved by purchasing inferior equipment. The gas turbine controls will be monitoring the turbine in ways human monitoring would be impossible. You will be glad if you get the most reliable gas turbine controls you can.
