Method for testing capability of synchronous generator in adjusting voltage of main transformer high-voltage side bus

Abstract

The invention provides an evaluation standard and a test method and discloses a method for testing the capability of a synchronous generator in adjusting the voltage of a main transformer high-voltage side bus, for solving the problem that there is not a concrete evaluation standard and a test method for evaluating and testing the capability of a conventional synchronous generator in regulating and controlling the voltage of a main transformer high-voltage side bus. The method comprises the following steps: running a detected synchronous generator under a load condition, and adjusting the active power of the synchronous generator to a predetermined value P; performing a voltage step test on the detected synchronous generator, calculating a ratio delta Us/delta Q of a voltage change value delta Us to a reactive power change value delta Q of the main transformer high-voltage side bus of the detected synchronous generator before and after the test; and establishing a relation curve between the predetermined value P and the ratio delta Us/delta Q. The test method brought forward by the invention combines testing with curve fitting and effectively tests the capability of the synchronous generator in regulating and controlling the voltage of the main transformer high-voltage side bus. A test result can be used for quite accurately evaluating the capability of the synchronous generator in regulating and controlling the voltage of the main transformer high-voltage side bus. Therefore, the method has quite high economic benefits and a quite high utility value.

AI Technical Summary

Benefits of technology

This patented technology describes an improved way to measure how well two different parts (the primary part) are connected together when they work properly. By testing them separately with both tools it becomes easier than just looking at one single thing alone.

Problems solved by technology

This patented describes how economically developed countries are increasingly turning towards larger generation capacity in order to meet their energy needs while reducing costs associated with generating electricity from fossil fuels like coal. However, there has been concern that these new sources may cause instabilities such as over voltages caused by sudden changes in load demand due to factors like weather conditions or other environmental issues affecting the quality of electrical distribution systems used at different locations around the world. These disturbances can lead to unstable grids which could result in damage accidents if they occur. Therefore, it becomes necessary to develop advanced techniques to monitor and prevent potential hazards related to this phenomenon called dynamic reactor compensation technology(VRCM).
