智能化云端蓄电池核对性放电试验控制监测装置的研制

随着国家电网推动泛在电力物联网的发展、电力设备智能化的提高，变电站站用直流系统蓄电池核对性放电试验存在工作人员需要人为监视放电试验全过程数十小时，容易造成工作人员现场工作时间长、精神压力大等问题，为此提出了智能化云端蓄电池核对性放电试验控制监测装置的研制。应用结果表明：该装置实现了工作人员不用在现场就可以随时随地监视蓄电池核对性放电试验全过程的关键参数，包括整组电压、单体电压（108节）、单体最高电压、单体最低电压（10节）、放电电流、放电时间等，放电情况不可靠时还可人为终止蓄电池核对性放电试验，本装置有效缩短了蓄电池核对性放电试验中工作人员在现场的工作时间，提高了直流系统日常维护的工作效率，进一步提高了变电站站用直流系统供电可靠性。

Research of intelligent cloud battery accurate discharge test control monitoring device

Making the research of the development and application of an intelligent cloud battery verification discharge test control monitoring device, the application results show that the device realizes that the staff can monitor the key parameters of the battery check discharge test process at any time and place without having to be on site, including the entire group voltage, cell voltage (108 sections), cell maximum voltage, cell the minimum voltage (10 knots), discharge current, discharge time, etc., can also artificially terminate the battery check discharge test when the discharge is unreliable. This device effectively shortens the working time of the staff in the field during the battery check discharge test, which improves the efficiency of the daily maintenance of the DC system,and further improves the reliability of the DC system power supply for the substation.
