Abstract

The invention discloses a safe and maintenance-free integrated power capacitor compensation module and a control method. The power capacitor compensation module is provided with a box-shaped shell, and a shell cover plate is provided on the top of the power capacitor compensation module. It is characterized in that: the box-shaped shell A circuit board is installed in the shell cavity, and a capacitor compartment is provided. The capacitor compartment is located below the circuit board and separated from the circuit board by an insulating insulating layer. The circuit board includes a control module, a wireless module, a switching switch, Power supply module, data acquisition module, etc. The power capacitor compensation module of the present invention is simple, maintenance-free, safe and reliable, and the control method of the present invention can ensure the correct identification of the reactive power compensation controller and the power capacitor compensation module in the same system in wireless communication, so as to reduce the cost of installation, commissioning and operation of the power distribution network. Labor hours and running costs required for maintenance.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a control method for reactive power compensation of a power distribution network. Background technique [0002] Power capacitors are circuit components that must be used for reactive power compensation in power systems. They play 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, in order to reduce the loss in power transmission and improve the capacity and quality of power transmission, it is necessary to compensate reactive power. However, the installation and wiring of existing power capacitors are generally more complicated, and the later maintenance is inconvenient, and the internal operation of the capacitor cannot be monitored. Contents of the invention [0003] Aiming at ...
