基于广义变比的换流站集成保护新方法
随着交直流混联输电技术的发展,换流站保护的研究日益重要。根据换流站交流母线电压和换流器输出直流电压之间的换流关系,定义了广义变比,提出了基于广义变比的换流站集成保护新方法。该方法运用集成保护的思想对换流站进行区域划分,利用广义变比实现换流元件异常或故障的实时在线监测,并根据换流变压器阀侧套管CT电流特征进行故障元件的准确定位。通过故障分析和EMTDC/PSCAD仿真验证,保护在换流元件各种故障情况下均能正确动作。...

Abstract_FL | With the development of AC and DC hybrid transmission technology, research on the protection of converter is becoming more and more important. According to the commutation relation between bus voltage of converter station and the output DC voltage of converter. The generalized ratio is defined, and a new method of converter station integrated protection based on generalized ratio is proposed. This method uses the idea of integrated protection to divide the converter station into regions.The generalized ratio is used to achieve real-time online monitoring of fault element anomalies and failures.And in accordance with CT current characteristics of the valve side of converter transformer bushing CT, it can accurately locate the fault current signature element. Through failure analysis and EMTDC/PSCAD simulation, protection under various fault conditions commutation element can operate correctly. |
