韶山换流站新一代调相机在非全相状态下的运行优化策略研究

在概述韶山换流站调相机工程概况、分析韶山换流站调相机工程调试现场非全相试验及结果的基础上,本文从保护和控制两个层面分别提出了非全相状态下的调相机运行优化方案。本文所提方案可有效解决调变组非全相保护在低无功出力时无法及时响应非全相状态的问题,对避免非全相状态下机组瞬时大无功出力对机组本体的损伤大有裨益,希望能为工程实际和相关电气从业人员提供有益参考。

Study on Operation Optimization Strategy of New Generation Phase Modifier of Shaoshan Converter Station Under Incomplete Phase State

In this paper,the operation optimization scheme on phase modifier under incomplete phase condition is proposed from such two aspects as protection and control on the basis of describing the outline of phase modifier of Shaoshan converter station and analyzing incomplete phase test and result of adjustment site of phase modifier of the converter station.The scheme proposed in this paper can solve the problem that the incomplete phase protection can’t respond to the incomplete phase state in time when the reactive power output is low,which is of great benefit to avoid the damage of the instantaneous large reactive power of condensers under the incomplete phase state.It is hoped that it can provide useful reference for engineering practice and related electrical workers.
