Coal Mine Voltage Fluctuation Analysis and Control Strategy

Abstract:

Reasonable allocation reactive power compensation devices in coal mine system can not only develop power factor, it can also solve bus voltage fluctuation problem of coal mine system. By analyzing load characteristic in coal mine system, non-linear impulse load and induction motor can cause bus voltage fluctuation. The characteristic of SVC is that its response speed is quick and it can be adjusted continuously. But the price of SVC is expensive. Reasonable allocation method is that a portion SVC is installed in the bus that are connected with a number of non-linear impulse load and induction motor, SVC is only used to undertake fluctuation load. It can solve voltage fluctuation problem well. Simulation and analysis on WSCC-9 bus system testifies the validation of the proposed method.
