Power Quality Improvement Equipment Reactive Power Compensation Device for Harsh Environments Durable Static Var Compensator

Static var compensation (SVC) is a kind of flexible AC transmission system (FACTS) device. It is mainly used for reactive power compensation and voltage regulation in power systems. Here is a detailed introduction:

Working Principle

SVC adjusts the reactive power output by controlling the reactance of the adjustable reactor and the capacitance of the fixed or adjustable capacitor. It can quickly respond to the changes of the power grid, absorbing or releasing reactive power to maintain the stability of the grid voltage and improve the power factor.

Advantages

• Fast response: It can quickly track the change of reactive power, effectively compensate for the reactive power deficiency or surplus in the grid, and improve the dynamic performance of the power grid.

• High reliability: With mature thyristor control technology and redundant design, SVC has high reliability and low failure rate.

• Wide range of applications: It is suitable for various power grid environments, such as substations, industrial power systems, and wind farms, and can meet different reactive power compensation requirements.

Applications

SVC is widely used in power systems, industrial enterprises, and new energy power generation. In power systems, it helps to maintain the stability of grid voltage, improve power quality, and reduce transmission line losses. In industrial enterprises, it can improve the power factor of equipment, reduce reactive power consumption, and save electricity costs. In new energy power generation, such as wind farms and photovoltaic power plants, SVC is used to deal with the reactive power fluctuation problem caused by the randomness and intermittency of new energy, ensuring the stable operation of the power grid.
