Voltage stabilizing system for electric transmission and transformation equipment

The invention provides a voltage stabilizing system for electric transmission and transformation equipment. The voltage stabilizing system comprises input voltage detection modules, a controller, a voltage compensation module and a voltage stabilizing circuit module. The input voltage detection modules are connected to the two ends of the equipment about to be subjected to voltage stabilizing and used for acquiring the current voltage value of the equipment about to be subjected to voltage stabilizing. The controller receives the current voltage value sent by the input voltage detection modules and compares the preset voltage value with the current voltage value, the compensating voltage value is obtained through calculation, and a voltage compensation command is set to the voltage compensation module according to the compensating voltage value. The voltage compensation module receives the voltage compensation command sent by the controller and is communicated with the voltage compensation circuit for voltage compensation operation. The voltage stabilizing module is arranged between the voltage compensation module and the equipment about to be subjected to voltage stabilizing. The voltage stabilizing system for the electric transmission and transformation equipment can well stabilize voltage and protect the equipment.
