In March 16, 2018, Wu Jia channel power supply company successfully completed the first charge and discharge test of the 102 regiment two Lian 110 thousand volt substation Germany sun battery group. The test data was qualified and the stable operation demand of the substation was met. It marked the successful completion of the replacement and transformation of the battery.
The six system of the 102 divisions of the agricultural two division 110 thousand volt substation uses the German solar battery A602/200A, a total of 104 pieces, and has been in operation for 14 years since its commissioning. Because of the long running years, the battery voltage is low and the total capacity of the battery pack can not meet the operation requirements in the recent test of the battery nuclear charge discharge test. The substation operation and maintenance team adopted several measures to ensure the successful completion of the transformation task. The class strictly according to the relevant regulations of the state Power Grid Corp "direct current power system management code", the production site operation "ten non dry" requirements and combined with the actual situation in the field to formulate reasonable construction plans, three measures and standardized operation guidance. The advance organizer is familiar with the basic principle and structure of the DC power supply system, mastering the wiring, operating mode and operating procedure of the DC system to prevent the accident of the DC power system caused by misoperation in the process of charging and discharging. Insulation of operation tools should be insulated in advance to avoid DC electric shock and short circuit during operation. Check the air conditioning and ventilation of the main control room in advance to ensure that the temperature of the main control room is within 5-35 degrees Celsius. The appearance of the new battery is checked in advance, and the voltage of the battery is measured by the multimeter. After the internal resistance of the German solar cell is measured by the internal resistance tester, the replacement work will be carried out again. After replacing the battery pack and charging it properly, the operation and maintenance personnel will proceed with the first charging and discharging test of the new battery.
The storage battery is the core of the DC system of the substation, which ensures the power supply of all kinds of DC loads and accident lighting under the substation's AC system failure. The healthy operation of the battery is directly related to the stable operation of the DC system, which further determines the reliability of the main system of the substation. The battery replacement work ensures the safe and stable operation of the DC system in the station, eliminates the hidden danger of the safe operation of the substation, and carries out the "spring inspection" work in order in 2018, and adds a guarantee to the healthy operation of the five channel power grid.
