    Abstract: This paper analyzed the problems that occurred during the commissioning process of a coal-fired motor control loop of a power plant, the failure conditions. In order to reduce the influence of the induced voltage of the AC long-distance control loop, the countermeasures such as changing the relay parameters, reducing the induced voltage and the generation of parasitic capacitance are proposed; and combined with the on-site situation, the method of inductance compensation is used to effectively suppress the influence of the induced voltage on the control loop.
    Key words: control circuit; induced voltage; distributed capacitance
