摘要

目前

换流器最后断路器保护存在可靠性差、逻辑复杂或预警性不足等问题，实际工程也出现了换流器最后断路器保护误出口事件。为此，文中首先梳理了实际工程换流器最后断路器保护的实现策略，并在换流器最后断路器电流回路特征分析的基础上，构造了虚拟交流出线电流网络和虚拟母线电流网络，继而提出了一种基于虚拟电流网络的换流器最后断路器保护算法，从原理上解决了最后断路器识别问题。所提算法与实际工程应用的算法进行了对比测试，测试结果表明所提算法可正确地识别最后断路器，原理清晰可靠

且有效地避免了实际工程中算法逻辑复杂、需要遍历等问题。

Abstract

At present

the last breaker protection for converter has the problems of poor reliability

complex logic or insufficient early warning

and there is an undesired tripping event of the last breaker protection for converter in practical project. Therefore

the realization strategy of last breaker protection in practical project is firstly sorted out. Based on the analysis of current loop characteristics of last breakers for converter in the paper

the current network of virtual AC line and virtual bus are constructed. Then

an algorithm of last breaker protection for converter is proposed based on the virtual current networks

which can solve the problem of identifying the last breaker for converter in principle. The proposed algorithm is compared with the algorithm used in practical engineering application

and the results demonstrate that the proposed algorithm can correctly identify the last breakers with clear and reliable principle

and avoid the problems of complex logic and the demand of traversing all working conditions.
