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.
