摘要

相较于机械式断路器，固态断路器（solid-state circuit breaker，SSCB）因其短路发生时切断电流无电弧及可靠性高的优点在直流电网短路保护中受到广泛关注。文中设计了一种具有自动隔离故障能力的直流固态断路器，该断路器由短路判定模块与故障电流缓冲模块组成，短路发生后可以在没有外部控制系统的情况下切除故障电流。文中对该固态断路器不同的工作状态进行分析，建立相应的数学模型，并以此作为参数设计的理论依据，在设计完成后与现有的固态断路器在10 kV/500 A直流电网的短路切除仿真中进行对比，仿真结果表明：加入具有自动隔离故障能力的直流固态断路器后，输电线的运行损耗仅增加0.025%，因此该断路器不影响电路的正常运行；当直流电网发生短路故障后，该断路器能在5 ms内自动关断，且可以平滑的吸收故障电流使固态开关所承受的峰值电压不超过线路电压的1.5倍，对直流电网具有可靠的保护作用。

Abstract

Solid state circuit breaker(SSCB)

compared with mechanical circuit breakers

has received much attention in short-circuit protection of DC network due to its such advantages as arc-free current interruption upon short circuit occurrence and high reliability. In this paper

a DC SSCB with automatic fault isolation capability is designed. The SSCB consists of a short-circuit judgement module and a fault current buffer module which

in case of short circuit

can clear the fault current without an external control system. The different operating states of this solid-state circuit breaker is analyzed

the corresponding mathematical model is set up and used as the theoretical basis for parameter design. After completion of the design

it is compared with the existing solid state circuit breaker in short circuit interuption simulation at 10 kV/500 A DCnetwork. The simulation result shows that after addition of the SSCB with automatic fault isolation capability

the operation loss of the transmission line is only increased by 0.025%

therefore the circuit breaker does not affect the normal operation of the circuit. After the occurrence of short circuit fault of the DC network

the circuit breaker can automatically interrupt within 5 ms and smoothly absorb the fault current so that the peak voltage sustained by the SSCB does not exceed 1.5 times the line voltage

thereby providing reliable protection for the DC network.
