what's reactive power compensation?

Everyone is aware that there are many inductive loads in the power grid. Basically, any device with a coil is an inductive load. During operation, corresponding reactive power needs to be supplied to these devices.

To solve this problem, the power supply unit requires the power-consuming units to install parallel capacitors and other devices for reactive power compensation, providing the reactive power needed by inductive loads. This reduces the reactive power that the power grid supply lines send to inductive loads. Thus, it not only alleviates the burden on the power grid transmission but also reduces energy loss. In simple terms, reactive power compensation is like this.

After understanding what reactive power compensation is, it will be easier to analyze the structure of the reactive power compensation cabinet.

Firstly, the compensation source is the capacitor. A capacitor is a device that stores electric charge. During the charging and discharging process, it performs its compensation function.

Secondly, the reactive power compensation controller, which is the brain of the entire electrical cabinet, can set and switch the compensation methods. It acts as a commander, following the principle of "supplement when insufficient and cut off when over-supplied" to control the input and removal of capacitors in the power grid.

Next, we come to the execution device. It is the reactive power compensation capacitor switch of the compensation cabinet. It is comparable to a soldier, turning on or off according to the instructions of the compensation instrument. Currently, most of the switches use thyristor switching devices.

In fact, the reactive power compensation cabinet is a device that, based on the specific conditions of the power grid, operates under the instructions of the intelligent reactive power compensation controller, by switching between input and output without interruption, to stabilize the power grid, improve the quality of power supply for use, and enhance the operational efficiency of the power grid. It is one of the essential power hardware in enterprise production.
