摘要
随着设备的老化及相关技术规范的完善,某电站直流系统亟需进行改造。基于对该电站直流电源系统的全面和深入分析,找出存在的缺陷,对接线方式、充电装置、蓄电池状态监测、绝缘监测系统等分别提出了完整的改造方案。实施改造后电站直流系统的运行状态及性能均优于改造前,验证了改造设计方案的合理性与可靠性。该电站的成功改造,可供其他电站直流电源系统的改造参考。
Considering the ageing of the equipment and the improvement of relevant technical specifications,the DC power supply system in a power station needs to be renovated urgently.A comprehensive and in-depth analysis of the DC power system is carried out to determine the existing defects.Then,a complete renovation scheme is proposed on the wiring mode,charging device,battery condition monitoring,and insulation monitoring system.After the renovation,the operation status and performance of the DC system are greatly improved,which verifies the rationality and reliability of the renovation scheme.The successful renovation of the DC power system in this power station can provide useful reference for other stations.
