摘　　要：电气工程师近年研制了许多微机式自动准同期并列装置。但是,都仍然采用模拟式自动准同期并列装置的方式,并没有发当今社会微机电脑的作用,限制了微机式自动准同期并列的作用。针对这种状况,基于单片机STM32自动准同期并列的硬件及软件的设计,通过硬件设计及软件编程自动调节三个并列因素,使之满足机组并列条件。可以进一步提高电网的精确度、快速性和可靠性。With the development of science and technology,the fluctuation of load is more and more serious,and the number of generators is often increasing or decreasing,so the automatic quasi-synchronization is one of the important operations in power system.Because of the increase of capacity,misoperation will lead to very serious consequences.Therefore,it is very important to improve the accuracy,rapidity and reliability of power system interconnection.At the earliest time,the"rotating light method"was used for grid connection in China;then,the manual quasi-synchronous parallel device consisting of a pointer electromagnetic winding step-by-step meter was adopted in China.In the 1980s,most parts of our country adopted the analog automatic quasi-synchronization device consisting of discrete devices.However,the instability of the analog device leads to many erroneous actions and accidents.Therefore,we design a digital parallel device based on STM32f103ZE MCU.Because of its simple hardware,convenient programming and mature development trend,it has become the main body of automatic quasi-synchronous parallel device in today's society.The device includes conditioning circuit,switching circuit,MCU,LCD.The designed micro-computer automatic quasi-synchronization parallel device has high reliability,rapidity and stability.
