    摘要:

    高压大容量长距离输电、恶劣气象环境与交直流故障耦合传播、大量电力电子装备的应用等因素给电力系统保护及安全控制带来了新的挑战。文中分析了设备故障原因、类型以及后果差异特征,提出构建电气设备主动保护与控制(简称PPC)技术体系。引入输变电设备安全域、动态安全裕度、设备安全耐受时间作为描述设备安全的主要特征量;提出了以设备安全域及安全参量预测为核心的主动保护与控制功能架构;分析了主动保护与控制技术涉及的主要技术方向,论述了电气设备主动保护与控制技术的可行性,给出了研究展望。

    Abstract:

    Power transmission of high voltage, large capacity and long distance, adverse meteorological environment, AC/DC fault coupling propagation, a large number of application of power electronic equipments and other factors have brought new challenges to power system protection and security control. Firstly, the causes and the types of transmission and trans-formation equipment faults, as well as the difference in fault consequences are analyzed in this paper, and the technical system of pro-active protection and control(PPC)of power equipment is proposed. Then, the concepts of security region, dynamic security margin and tolerance time for safety of power transmission and transformation equipment are proposed to describe the safety of equipment as the main features. The technical architecture of pro-active protection and control is further proposed cored on the prediction of security region and security parameters of equipments. Finally, main technical directions of the pro-active protection and control are analyzed in this paper, and feasibility of the corresponding key technology, and prospect of the pro-active protection and control are discussed.
