1, auxiliary transformer and auxiliary reactor can run in parallel because they play different roles in power system.
2. Auxiliary transformers are mainly used to change voltage, transmit high voltage to remote users, or upgrade low voltage to suitable high voltage. The function of transformer is to provide voltage conversion needed in the process of transmission and distribution.
3. Auxiliary reactor is a kind of reactive power compensation equipment, which is used to compensate reactive power in power system. Reactive power is a kind of virtual work in power system. It does not do work, but it will cause voltage fluctuation and current fluctuation in the power system. Reactors can balance the reactive power in the power system by providing reactive power, thus maintaining the stable operation of the power system.
4. Because of the complementary function of auxiliary transformer and auxiliary reactor in power system, they can run in parallel. Transformers provide voltage conversion function, transmit electric energy to distant users, and reactors provide reactive power compensation function to balance reactive power in power system. By running in parallel, auxiliary transformer and auxiliary reactor can maintain the stable operation of power system.
