Automatic reactive power regulator
专利汇可以提供Automatic reactive power regulator专利检索，专利查询，专利分析的服务。并且PURPOSE: To simplify a circuit constitution by comparing the output of a reactive power detector and an established value of reactive power; providing a comparator integrator which performs integrating operation corresponding to the difference resulted from the above comparison; and adding the output to the standard of an automatic voltage regulator.
CONSTITUTION: When the reactive power of a synchronous machine varies, the output of a reactive-power detector 11-1, to which the output of a transformer 1 and a current transformer 7 are given, is compared with the value of a reactive power setting unit 11-2; and its difference is integrated by an integrator 11-3; thereafter it is applied to the input of an amplifier 2-2 of an automatic voltage regulator 2. Then, the output depending on the sum of the outputs of a voltage detector 2-1 and the integrator 11-3 is applied to a phase-control device 8, and controls the gate of a thyristor rectifier 9, thereby the field voltage is controlled. Therefre, the voltage- regulating register of the voltage regulator is not required to be regulated by a relay and a motor, the constitution is simplified, and reliability and maintenability can be enhanced.
