The SVC is made up of controllable reactance, passive filters (FC), and control and protection unit. At present, terms of the principle on which the reactance is adjusted, static var compensators are classified into three types: thyristor-controlled transformer (TCR), thyristor-controlled reactor (TCR), magnetic-controlled reactor (MCR). For their working principle and difference, see “SVC Operating Principle
SENBAO has developed all the three types of static var compensator and launched them on the market successfully. As the only manufacturer in China possessing proprietary intellectual property right of the three types of SVC, SENBAO offers the best performance-to-cost SVC solutions and complete set of equipment to fulfill user requirements.

Features
- TCR-type SVC
- 1. Fast response in 10 ms.
- 2. High power capability up to hundreds of Mvar, but cannot be connected directly to Ultra High Voltage (UHV).
- TCT-type SVC
- 1.Fast response is same as in TCR-type.
- 2. As the voltage is stepped down through TCT to 1000～2000V, the thyristors are operating at a relatively low voltage and high-voltage thyristor valves can be dispensed with at all, thus greatly simplifiying the configuration and enhancing the security and reliability of the system. Moreover, lower working voltage makes the operation and maintenance of the thyristors much easier.
- 3.TCT transformer and reactors combo has better overload capability and small footprint.TCT transformer and reactors combo has better overload capability and small footprint.
- 4.Can be applied to UHV systems.Can be applied to UHV systems.
- MCR-type SVC MCR-type SVC
- 1 In MCR-type SVC, no high-power thyristor valve is needed for compensating capacity control, resulting in small footprint and simple structure. Adoption of magnetic control increases the reliabilty of SVC system substantially, maintenace free in 20 years.
- 2.Advanced techniques such as self-coupling excitation and limiting magnetic saturation not only produce much smaller harmonics, but also reduce real power losses, fast responding, and without generating electro-magnetic radiations.
- 3.Can be applied to UHV systems.Can be applied to UHV systems.
