摘　　要：以广东梅州电网为例,分析500 kV变压器有载调压对下层电网电压和无功功率的调节效应,论证500 kV有载调压变压器在广东电网的适用条件。根据广东电网存在的电压调控问题,以梅州电网为代表建模,分别对夏季小方式、冬季小方式下发电厂定电压运行、定无功功率运行工况进行调压效应分析,并总结出规律,指出对500 kV有载调压变压器参与电压调控的要求。The paper takes Meizhou grid as an example to analyze effect of OLTC of 500 kV transformers on subgrid voltage and reactive power, and it discusses service condition of 500 kV OLTC transformer in Guangdong. In accordance to voltage control in Guangdong power grid, a model is built and working condition of stable voltage and reactive power in summer/ winter operation mode is analyzed and rules are summarized. Requirements of voltage control on 500 kV OLTC transformer are presented.
