摘要
在对火力发电厂运行中的关键监测点电能质量指标进行专门测试与评估分析时发现,火力发电厂部分厂用电母线电压波动存在超标现象。在对多个火力发电厂的电能质量指标进行测试的基础上,计算并分析厂内高压系统及中压系统对应监测点的三相电压波动数据,并将测试结果与国标限值进行比对后给出了评估结果和合理化建议。
In the special test and evaluation analysis of the power quality indices at key monitoring points in the operation of a thermal power plant,it is found that the voltage fluctuations of some auxiliary power buses in the thermal power plant exceed their standard limits.At this point,based on the testing of power quality indices of multiple thermal power plants,the three-phase voltage fluctuation data of the corresponding monitoring points in high voltage and medium voltage systems in the plants are calculated and analyzed,and the test results are compared with the national standard limits,the evaluation results and reasonable suggestions are given.
