Description

technical field [0001] The invention relates to a device in the field of power system technology, in particular to a voltage and reactive power comprehensive control device based on a magnetron reactor. Background technique [0002] At present, the reactive power compensation in the power system substation is generally switched by the circuit breaker capacitor bank. With the gradual increase of cable lines in the power system, when the load is light, these capacitive reactive powers appear to be excessive. It is difficult for traditional SVCs to compensate these capacitive reactive powers, resulting in high system voltage and unbalanced reactive power, which affects system stability. And the safety of electrical equipment is not conducive to the stable and efficient operation of the power system. Thyristor phase control (TCR) uses thyristor-controlled reactors to compensate reactive power. The control process is executed quickly, and the range of reactive power compensation...
