[0002] During the operation and maintenance process of substations, there are many problems. Among them, the substation power supply device is an important link to ensure the safe and reliable operation of the substation. It mainly consists of three major parts: the substation AC power supply system, the DC power supply system, and the AC uninterruptible power supply system. In the DC power supply system, the monitoring and management unit is responsible for the control and management of functional units such as the charger, battery pack, and insulation monitoring device. In the AC power supply system, the basic parameters of the monitoring unit determine the control mode, switching action time, and abnormal alarm setting value of the automatic transfer switch - ATS. If the parameter settings of the monitoring unit are incorrect or unreasonable, it will seriously affect the operating conditions and combined configurations of the functional units in the DC power supply system and the AC power supply system. Therefore, the parameter configuration management of the monitoring and management unit is particularly important.

[0061] A method for verifying parameters of a station power supply device provided by the present invention includes:

[0062] Step 101: When receiving a parameter verification request for a station power supply device, determine the verification item corresponding to the parameter verification request for the station power supply device.

[0063] The parameter verification request for the station power supply device refers to a request sent by a staff member during the inspection operation of the station power supply device to determine whether the parameters of the station power supply device are abnormal in order to verify the correctness of the parameter settings of the station power supply device. For example, whether the parameters of the DC voltage system monitoring unit are abnormal, whether the parameters of the AC power system monitoring unit are abnormal, and whether the parameters of the upstream and downstream circuit breakers of the AC feeder are abnormal.

[0064] In an embodiment of the present application, when receiving a parameter verification request for a station power supply device sent by a staff member, read the request, obtain the parameter management system to be verified, and match the corresponding verification item according to the parameter management system to be verified.

[0065] Step 102: According to the verification item, obtain the basic data and target setting value of the station power supply device.

[0066] The basic data refers to the parameters measured by the station power supply device under the rated state. For example, DC rated voltage, bus rated voltage, charger rated voltage, capacity of the battery pack, number of battery cells in the battery pack, floating charge and equalizing charge voltage values, AC rated voltage, transformation ratio of the AC incoming line current transformer, total station load, starting current of the total station fire pump, and model data of the first-stage air switch.

[0067] The target setting value refers to the setting value of the parameter management system of the station service power supply device. It includes, but is not limited to, the AC input overvoltage value, the AC input undervoltage value, the charger output overvoltage value, the charger output undervoltage value, the power bus overvoltage value, the power bus undervoltage value, the control bus overvoltage value, the control bus undervoltage value, the overvoltage setting value, the low voltage setting value, the rated current value of the incoming line switch, and the model data of the secondary air switch.

[0069] Step 103: Calculate the standard setting value of the station service power supply device according to the basic data.

[0070] The standard setting value refers to the equipment setting value of the station service power supply device when it is working normally. When the actual operation value of the equipment exceeds the equipment setting value, it can trigger the action of the relay protection equipment, which can play a role in ensuring the safe operation of the equipment and is used to judge whether the parameters of the station service power supply device are abnormal.

[0071] In the embodiment of the present application, the basic data is obtained, and the standard setting value of the station service power supply device is calculated.

[0073] In the embodiment of the present application, after obtaining the target setting value and the standard setting value of the station service power supply device, they are compared. If the target setting value is not within the range of the standard setting value, it is determined that the parameters of the station service power supply device are abnormal; if the target setting value is within the range of the standard setting value, it is determined that the parameters of the station service power supply device are normal.

By comparing the target setting value with the standard setting value, if the target setting value is not within the range of the standard setting value, it is determined that the parameters of the station power supply device are abnormal; if the target setting value is within the range of the standard setting value, it is determined that the parameters of the station power supply device are normal. The entire calculation process does not require the staff to consult materials and the manufacturer to configure to determine the corresponding parameter range, and can accurately judge whether the parameters of the station power supply device are abnormal, improving the efficiency of setting value management work and reducing the complicated workload of on-site staff.

[0075] Please refer to Figure 2 , Figure 2 which is the step flowchart of a method for verifying the parameters of a station power supply device provided in the second embodiment of the present invention.

[0117] The undervoltage threshold of the power bus refers to the ratio of the voltage value that the power bus line cannot be lower than under the rated state to the rated voltage of the bus.

[0118] In this embodiment, after obtaining the rated voltage of the bus, calculate the fifth multiplication value between the rated voltage of the bus and the overvoltage threshold of the power bus, and then calculate the sixth multiplication value between the rated voltage of the bus and the undervoltage threshold of the power bus, where the fifth multiplication value is the basis for judging whether the overvoltage value of the power bus is abnormal, and the sixth multiplication value is the basis for judging whether the undervoltage value of the power bus is abnormal.

[0133] It should be noted that the rated current value of the incoming line switch plays a role in protecting against overcurrent of the incoming line. Its rated current value of the incoming line switch should be greater than the sum of the total station load and the starting current of the total station fire pump to ensure that it does not malfunction when a single working transformer supplies the total station load. Therefore, the first sum value is the basis for determining whether the rated current value of the incoming line switch is abnormal.
