Characteristics of frequency converter for coolant pump of AP1000 nuclear power plant and optimization of power supply circuit

Abstract

Abstract: The equipment parameters and the practical operation condition of the coolant pump of domestic AP1000 nuclear reactor request higher performance of the coolant pump frequency converter. The characteristics and performance of the coolant pump frequency converter for AP1000 nuclear power plant were expounded from three aspects, which are the structure of the device, the control and protection mode and the operation features of the coolant pump converter. The optimization measures for the power supply circuit of the coolant pump were put forward, which can increase the reliability of the power supply for the motor of the coolant pump.

Key words: AP1000 nuclear power plant, coolant pump, frequency converter, power unit, water cooling, redundancy, drift of neutral point
