The invention discloses a reactive power compensation device monitoring system, which comprises a reactive power compensation device and a measurement and control device, the measurement and control device comprises a data acquisition module and an output module which are connected with the reactive power compensation device, a control module which is connected with the data acquisition module andthe output module, and a monitoring module which is connected to the control module; and the data acquisition module acquires a circuit data signal in the reactive power compensation device in real time and sends the circuit data signal to the control module, the control module sends the circuit data signal to the monitoring module, and the monitoring module converts the circuit data signal intoa frequency signal and compares a frequency value in the frequency signal with an early warning value V. A power factor controller in the reactive power compensation device monitoring system can monitor whether the reactive power compensation device is still effective or not in real time, oscillation of the power supply system is avoided, and normal operation of the power supply system is protected.
Description
technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a reactive power compensation device monitoring system. Background technique [0002] Reactive power compensation plays a role in improving the power factor of the power grid in the power supply system, reducing the loss of power supply transformers and transmission lines, improving power supply efficiency, and improving the power supply environment. Therefore, the reactive power compensation device is in an indispensable and very important position in the power supply system. Reasonable selection of reactive power compensation device can minimize the loss of the power grid. In the 400V power supply system, the existing power factor controller cannot judge whether the reactive power compensation device is still effective, nor can it judge when the reactive power compensation device needs to be replaced, resulting in the inability to well control the loss of the ...
