Abstract:

Because of the special wiring forms and operation characteristics, it is difficult to monitor the actual running index of power quality for the thermal power plant. In order to grasp the power quality indicators of thermal power plant operation comprehensively and accurately, special testing and evaluation for the power quality is necessary. The current power quality testing for thermal power plants is less and lacks comprehensiveness. Based on the testing of the power quality indicators of several thermal power plants, the power quality data of key monitoring points such as the generator outlet, booster station bus, and factory power bus were calculated and analyzed. Then the test results were correlated with the relevant national standards. Finally, the assessment results and reasonable recommendations were given.

Key words: thermal power plant, power quality test, evaluation analysis
