Technical Field

[0001] The invention relates to the technical field of substation simulation, and in particular to a method for updating a multi-parameter simulation model of a substation. Background Art

[0002] The substation setting simulation system is a system based on virtual reality 3D technology and aimed at the safe production of intelligent substations. The system simulates intelligent primary equipment and deep secondary equipment to achieve high-precision and realistic display of three-dimensional substations. It can carry out equipment inspections, switching operations and accident handling training for operation and maintenance stations, thereby improving the actual operation ability and abnormal and accident handling ability of operation and maintenance personnel, which is conducive to the safe production of intelligent substations. In the simulation system of the substation, the simulation model needs to be updated regularly according to the actual situation of the substation to ensure more accurate simulation effects;

[0003] However, in the process of updating the substation simulation model, the adjustment of parameters is not detailed enough, and the simulation effect of the substation is not good. It is necessary to accurately update the substation simulation model. Summary of the invention

[0004] The present invention provides a method for updating a multi-parameter simulation model of a substation, which can effectively solve the problem raised in the above background technology that during the updating process of the substation simulation model, the adjustment of parameters is not detailed enough, the simulation effect of the substation is not good, and the substation simulation model needs to be accurately updated.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for updating a multi-parameter simulation model of a substation, comprising the following updating steps:

[0006] S1. During the steady-state and transient processes of the substation, the original parameters of the equipment model are recorded, and simulation input data are input into the substation model respectively to obtain the first simulation output data;

[0007] S2, by changing the equipment model parameters of the primary simulation system and the secondary simulation system of the substation, inputting the same simulation input data again, recording the action of the equipment model, and obtaining the second simulation output data;

[0008] S3, analyzing the equipment model action, analyzing the second simulation output data according to the actual input data, output data, actual equipment parameters, equipment model parameters before and after the change, and the first simulation output data of the substation;

[0009] S4, determining whether the second simulation output data has an abnormality, and determining an output device for the abnormal data;

[0010] S5. Detecting the input data of the abnormal data output device to determine the source of the abnormal data;

[0011] S6. Finally, determine the scope of equipment affected by the abnormal data;

[0012] S7, updating the equipment in the substation model;

[0013] S8. Detect the equipment in the updated substation model to determine the usage of the updated equipment.

[0014] According to the above technical solution, in S1, after the substation system enters a steady state, simulation input data is input, transient simulation is performed on the substation system, and simulation output data is obtained;

[0015] The simulation input data is set to be greater than 3 groups, and the corresponding first simulation output data and second simulation output data are obtained.

[0016] According to the above technical solution, in S2, when adjusting the parameters, the parameters of one device involved in the simulation data are adjusted each time;

[0017] After adjusting the parameters, obtain the second simulation output data, restore the adjusted parameters, and adjust the parameters of another device until all the devices involved have their parameters adjusted once;

[0018] Each time the device parameters are adjusted, a set of second simulation output data is obtained.

[0019] According to the above technical solution, in S2 and S3, the adjustable parameters of the substation equipment include ambient temperature, operating humidity, power input, rated test capacity, resonant voltage, frequency adjustment range, system measurement accuracy, frequency adjustment resolution and reactor Q value;

[0020] The output data of substation equipment includes rated voltage, rated current, no-load loss, load loss, impedance voltage and voltage regulation range.

[0021] According to the above technical solution, in S3, the second simulation output data is inferred according to the change of parameters, and the inferred data is compared with the actual second simulation output data. If the two are the same, the output is normal, and if they are different, abnormal data exists.

[0022] According to the above technical solution, in S4, the actual input data, output data, and actual equipment parameters of the substation are compared and analyzed with the simulation input data, the first simulation output data, and the second simulation output data to determine the abnormal conditions between the data.

[0023] According to the above technical solution, in S4 and S5, the output device is first determined according to the input and output paths of the abnormal data and the participating devices;

[0024] After the output device of the abnormal data is determined, the input data of the device is determined, the source of the data is found according to the data transmission path, and the generation location of the abnormal data is analyzed in turn.

[0025] According to the above technical solution, in S6, the devices affected by the abnormal data include an output device of the abnormal data, a transmission device of the abnormal data and an input device of the abnormal data;

[0026] Among them, the input device of abnormal data and the output device of abnormal data are devices with determined impact, and the transmission device of abnormal data is a device with pending impact;

[0027] For devices with pending impact, secondary testing is required to determine whether the device is abnormal by inputting normal data and testing whether the output data is abnormal.

[0028] According to the above technical solution, in S7-S8, the affected devices are first determined, then the connection relationship of the devices is determined, and finally the devices are updated;

[0029] When updating a device, first repair the device itself, then input data to test the repaired device. If no abnormality is detected, the update is complete.

[0030] The data is taken in to detect the repaired equipment. If an abnormality is detected, a new device is used for update. The data is input to detect the usage of the new equipment in the substation system. If no abnormality is detected, the update is completed.

[0031] According to the above technical solution, in S8, after all equipment in the substation system is updated, the simulation input data is input into the substation system again to obtain the simulation output data after detection, and the simulation output data is analyzed to determine the usage of the updated equipment in the overall substation system.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. By inputting simulation input data into the substation simulation system, obtaining the first simulation output data, and then comparing it with the actual data, determining the difference between the data, and updating the equipment parameters, the simulation data is closer to the actual data, so that multiple parameters of the equipment are more consistent with the actual substation, making the simulation effect of the substation better.

[0034] 2. By analyzing the data in the actual substation and the substation simulation system, the abnormal data is analyzed to find the corresponding equipment, and the equipment involved in the abnormal data is analyzed in turn to update the abnormal equipment, so that the model equipment in the substation simulation system can be better simulated.

[0035] In summary, by comparing and analyzing the simulation data with the actual data, the parameters of the substation simulation model are updated, so that the simulation effect is closer to the actual effect and the accuracy of the simulation is increased. At the same time, the abnormal model equipment in the substation simulation system is analyzed and updated by repairing and replacing, which can better improve the efficiency of model utilization in the substation simulation system.
