摘要
设计并研制了一种新型直流系统在线监测装置,可实现对配网自动化成套保护设备直流电源系统的在线监测,并能以无线或光纤通信的方式,完成三遥信息在配网自动化站点和配网自动化主站间的加密传输,并实现通信加密模块故障原因的自诊断,从而能有效地排查各自动化站点直流电源系统运行状态,快速确定通信加密模块失效原因,方便运维人员制定检修计划,提升直流电源系统和通信加密模块的维护水平。实测表明,新型直流系统在线监测装置能实现直流电源在线监测,自检通信加密模块功能终端故障原因,对实现配网高可靠性运行有一定实用价值。
which can realize on-line monitoring for DC power system of complete set of protection equipment for distribution network automation.This device can complete encrypted transmission of three remote information between distribution automation site and main station of distribution automation by wireless or optical communication,and realize self-diagnosis of the causes of the faults of communication encryption module,so as to effectively troubleshoot the operation status of DC power system in each automation site,quickly determine the causes of the failure of communication encryption module,facilitate maintenance personnel to make maintenance plans,and improve the maintenance level of DC power system and communication encryption module.The test results show that the new on-line monitoring device of DC system can realize on-line monitoring of DC power supply,and the cause of terminal failure of self-checking communication encryption module function has a certain practical value for realizing high reliability operation of distribution network.
