摘要/Abstract

摘要：

2020年底投运的张北特高压站汇集的5 000 MW电力均为新能源。从新能源出力的不确定性角度来看,张北—北京西线路潮流将在0~5 000 MW之间变化。针对该不确定性,首次应用了特高压分级式可控并联电抗器(controllable shunt reactor,CSR)成套装置,解决了特高压输电系统中无功补偿和限制过电压对并联电抗器不同需求之间的矛盾,降低了无功损耗,提高了系统调控灵活性,为张北地区新能源外送创造有利条件。示范应用中在工程选点、集成设计、设备研制等方面均有创新。如可结合新能源外送特高压通道上电压波动频繁且幅度较大等问题开展工程选点;特高压CSR本体、晶闸管阀等设备的集约化设计思路提高了产品经济性。通过分析系统试验阶段以及设备投运一年来的数据,提出了特高压分级式CSR工程应用技术的优化方向。

Abstract:

The 5 000 MW power collected by Zhangbei UHV substation put into operation at the end of 2020 is new energy. From the perspective of uncertainty of new energy output, the power flow of Zhangbei-Beijingxi line will change between 0 MW and 5 000 MW. Aiming at the uncertainty, a complete set of UHV hierarchical controllable shunt reactor (CSR) is applied for the first time. It solves the contradiction between reactive power compensation and limiting overvoltage on different requirements of shunt reactor in UHV transmission system, reduces reactive power loss, improves the flexibility of system regulation, and creates favorable conditions for the export of new energy in Zhangbei area. In the process of realizing the application of the first UHV CSR demonstration project, a series of innovative achievements have been made in integrated design and equipment development. The project selection starts with the problems of frequent and large voltage fluctuation on the UHV channel of new energy export. In the integrated design, the intensive design concept of CSR and thyristor valve lays the foundation for economy. These innovative achievements in the power system test stage and more than one year of actual operation of the UHV CSR are analyzed and summarized, and the optimization direction is put forward.
