摘要
针对电力直流系统设计过程中保护元件如何正确选型及上下级之间选择性保护的配合校验问题,开发了一种直流电源系统保护元件级差配合校核软件,实现了对变电站/电厂直流系统线路配置设计、保护元件选型、灵敏度和选择性校验等功能。该软件不仅能够对已有的直流电源系统进行分析,同时也能够对新站的建设起到辅助设计作用,是直流系统设计人员得力的辅助设计工具。
An application software for stage difference coordination verification of protective device in DC sys-tem was developed,aiming at the problems of the selection and the stage difference coordination verification of pro-tective device.This appication software had many functions,such as sketch design,protective devices selection and the verification of sensitivity and selectivity,which made it not only suitable for the analysis of exsiting DC system,but also for the design of DC system as an aided design tool.
