Description

technical field [0001] The invention relates to a wireless communication control system for a capacitance compensation cabinet in a power transmission network. Background technique [0002] In modern industrial production, since the vast majority of electrical equipment are inductive loads, the power factor is obviously less than 1 during operation, and a large amount of reactive power needs to be taken from the power system. Therefore, in order to improve the power factor of the system, it is necessary Compensate the reactive power in the grid system. In order to stabilize the grid terminal voltage, improve the quality of power supply; improve the power factor of the system and load, reduce capacity and equipment investment; reduce line loss, improve the transmission capacity of grid active power; balance the three-phase active power and reactive power of the grid; reduce transformer loss , Improve transformer utilization, etc. It can be seen that reactive power compensat...

Problems solved by technology

[0003] In the current reactive power compensation technology, the composite switch switching method is generally used in the switching method of the capacitor. Since the thyristor is used in the composite switch, it is easy to break down the thyristor due to the instantaneous voltage during switching. As a result, the module cannot work normally and affects production; secondly, the current capacitor communication uses the network cable connection for online communication to perform reactive power compensation, but the quality and loss of the network cable have a certain impact on the online communication of the capacitor. will cause hidden danger
