The main function of the voltage regulator

Voltage regulator has the following functions: ① maintain the generator voltage for a given level. As the load current changes affecting the terminal voltage of the generator terminal voltage variation is too large power systems and electrical equipment will produceelectric transformer many unfavorable factors and problems, so the generator excitation current must adapt to changes in voltage, give prompt and timely automatically adjusted. ② reasonable distribution of the load between paralleled generator sets. Grid by multiple generators operating in parallel, the load borne by each unit should be a reasonable allocation, otherwise it will cause some generator overload. Thus, the desired voltage regulatorElectric transformer according to the rules specified in the network load balancing smoothly. This feature is also known as the voltage regulator droop function. ③ improve the power system stability.
