摘要

混合式高压直流断路器是目前处理直流电网故障较为认可的一种方式

但其存在造价昂贵、使用个数多等问题。为有效解决此类弊端

提出一种电流转移型高压直流断路器

并对其故障隔离控制时序进行了研究。电流转移型高压直流断路器借鉴了混合式高压直流断路器的关键部件和设计理念

将直流母线以及与其相连的混合式直流断路器进行了整合

以整体概念对断路器进行了再设计

优化了设备利用价值。在保证同等直流故障处理能力的前提下

相比混合式高压直流断路器

其投资成本大幅度降低。为验证电流转移型高压直流断路器的有效性

在PSCAD/EMTDC内建立了一个三端单极直流网络模型。仿真结果验证了电流转移型高压直流断路器在隔离直流线路故障方面的可行性和有效性。

Abstract

Currently

the hybrid high voltage direct current(HVDC)breaker is recognized as a way to deal with the DC grid fault despite its expensive cost

more breakers used

etc. To remedy the situation

a current-transferring type HVDC breaker is proposed and the control sequence of fault isolation for the break is studied. By drawing on the key components and design philosophy of the hybrid HVDC breaker

the DC bus and the hybrid HVDC breakers connected to the same DC bus are integrated in the current-transferring type HVDC breaker. By redesigning the HVDC breaker with the overall concept

the equipment utilization value is optimized. On the premise of ensured breaker ability of handling DC-side fault at competitively low cost

its operating speed is as fast as the hybrid HVDC breaker. A model of a three-terminal monopolar HVDC grid is developed in PSCAD/EMTDC to verify the validity of the proposed breaker

with the validity and feasibility of the proposed solution verified by simulation results.
