摘要
电网舞动分布图作为在运输电线路防舞治理及新建线路防舞设计的依据,在确保电网安全稳定运行中发挥着重要作用。继频次法后,气象地理法作为不考虑实际线路影响的舞动分布图绘制方法在国家电网公司范围内得到了推广应用,针对气象地理法在绘制舞动分布图时,采用逐日气象数据可能带来较大的舞动气象日计算误差的问题,提出了以逐时气象数据为基础开展舞动分布图绘制的方法 ,并以浙江省为例介绍了该方法的可行性。
Power grid galloping region distribution map is basis of prevention and treatment of transmission lines galloping during construction and operation phases. It plays an important role in power grid operation safety and stability. In addition to frequency method, the meteorological geographical method is used widely in SGCC as a drawing method for galloping region distribution map without consideration of influence from actual lines. In order to reduce galloping meteorological calculation error resulted from daily meteorological data, a new drawing method based on hourly meteorological data is proposed. The application results in Zhejiang province shows the feasibility of proposed method.
