| Abstract |
The purpose of the static starting equipment(SSE) is to accelerate a synchronous machine up to a speed at which it can begin to run on its own. Because of its compressor, gas turbine must be run up to about 20 30% of its rated speed before it is capable ∼ itself of producing enough power to continue accelerating the set. Recent korea researchers have developed the 10MW startup equipment based on the accumulated high power conversion technology. The 10MW startup equipment, which is scheduled to be applied to the B power plant, is equipped with the latest sensorless speed control technology. It was tested for checking performance before applying to the site. In this paper, the contents of the performance test were described. The performance test for 10MW startup equipment was carried out in two stages. The first stage of the test was performed without being linked with synchronous machine. The purpose of the test was to verify the developed hardware, basic control loop etc. In case of power conversion, the current control function was tested by shorting the converter. The two-stage test was carried out on a simulated environment using 2MW M/G system test facility. Basically, the test is for all function check of starting equipment. By estimated position and speed, It accelerated rotor until rated speed. Various performance evaluation results came out from the last tests before the field application.
The performance of each control mode was satisfactory and the applied technology is expected to be well used for starting equipment. |
