摘　　要：针对目前一次调频性能评价方法不能准确描述所有一次调频过程的问题,提出特高压跳闸事故下的一次调频性能评价方法。通过对比正常情况下一次调频过程的统计结果,得出特高压跳闸事故下一次调频过程的特性。基于该特性构建新的性能评价指标体系,同时对原性能评价指标存在的问题进行补充完善。可对特高压跳闸事故后不同机组的一次调频动作过程进行精确的区分描述,并在河南电网环特高压重点电厂网源协调专项检查中得到应用,对一次调频的综合治理和特高压跳闸事故恢复提供数据参考和指导依据。For the converter station located in a sandy area, the dust will cause harmful impact on electrical equipment, buildings and structures in the station, and even threaten the safe operation of the station. Along with a large number of UHV DC projects planned in the sandstorm-prone areas in northwest China, it is thus imperative to carry out an in-depth study on the sand-prevention measures for the converter stations to ensure their successful construction and operation. Based on an investigation on the design and operation situation of the existing converter stations in sandy area, a summary and analysis is made on the specific sand-prevention measures for the electrical equipment, buildings and structures of the convertor station, which cab provide a technical support and reference to the design of the sand-prevention measures for the future power transformation projects, especially the UHV DC converter stations in the sandy area.
