Power generation module and control method thereof, and dual-power automatic transfer switch controller

Abstract

The invention discloses a power generation module, which is used for dual-power automatic transfer switching equipment with a standby power supply as a generator. The power generation module comprisesan auxiliary power supply, a power conversion circuit, a control switch, a module interface circuit, a power generation execution circuit, and a power generation module control unit, wherein the power generation module control unit is used for enabling the control switch to be turned on and sending a generator start command to the power generation execution circuit after the first delay time whena common power supply abnormal signal sent by a dual-power automatic transfer switching equipment controller body is received; or when a cancel signal sent by the dual-power automatic transfer switching equipment controller body is received or the cancel signal is not received after the second delay time, turning off the control switch. The invention further discloses a control method of the power generation module and the dual-power automatic transfer switching equipment. The power generation module provided by the invention can realize a power generation delay function of the dual-power automatic transfer switching equipment, and solve the problem that the auxiliary power supply is not provided on the site and power consumption of a battery is too fast due to capacity limitation.

Description

technical field [0001] The invention relates to a power generation module with low power consumption, which is used for a dual power supply automatic transfer switch controller in which the backup power source is a generator. Background technique [0002] With the development of electronic technology and the diversity of user needs, dual power supply products are becoming more and more powerful, and are developing in the direction of modularization. At present, dual-power automatic transfer switches with generators (generally diesel generator sets) as standby power sources are widely used to ensure the reliability of power supply for important users. The power generation function is available as a module for users to choose, and it is more flexible when it is used in the occasion where the backup power source is a generator. During the application process, when the power grid is abnormal, the power generation module receives the power grid abnormality signal sent by the aut...
