特高压受端电网负荷批量控制策略研究与应用

Study on the Load Batch Control Strategy of the Extra-High Voltage

摘要: 传统电网事故限电通常采用人工计算、按限电序位表逐条限电模式，事故处置效率低、限电时间长、易造成停电范围扩大。近年来，随着特高压电网的发展，如何应对特高压直流突发大功率运行故障重大紧急情况成为研究的热点。针对传统事故限电模式存在的问题，开展优化研究，提出负荷批量控制策略。通过实操演练，验证了负荷批量控制功能的快速性、智能性、安全性，并积累了负荷批量控制实际操作经验。

Abstract: Traditional limited power grid accidents are usually made by manual calculation, and the pow-er-limiting sequence. The efficiency of the accident is low, the power limit is long, and the power failure can be extended. In recent years, with the development of ultra-high voltage power grid, how to deal with the major emergency situation of high-voltage dc burst power failure has become a hot topic. Aiming at the existing problems of the traditional accident limiting mode, this paper conducts optimization research and puts forward the load batch control strategy. Through the practice of practice, the speed, intelligence and security of load batch control function are verified, and the actual operation experience of load batch control is accumulated.
