摘要
自动准同期装置是为实现同步发电机快速并入舰船电力系统而设计的专用仪器,它能控制发电机快速满足准同期条件,从而实现准确、安全并网。本文探讨了发电机安全并入电网所需的准同期条件,并详细介绍了自动准同期装置的原理以及软硬件设计。设计中采用MCS-51系列单片机构成最小系统,应用大规模可编程逻辑器件简化逻辑设计,从而设计出具有智能化的并网设备。该装置已经形成产品并投入使用,效果良好,具有很高的推广价值。
Auto Quasi Corresponding-period Equipment is designed to realize a generator＇ rapid parallel connection to electrical network in a power plant. It can control the generator to fulfill Quasi Corresponding-period Condition rapidly, and then realize accurate and safe parallel connection. At first this paper discusses Quasi Corresponding-period Condition, which must be fulfilled by a generator for safe parallel connection, and then the theory and software and hardware design of Auto Quasi Corresponding-period Equipment are introduced. With MCS-51 family Single Chip Micyoco （SCM） and Large Scale Programmable Logical Device （PLD）, a kind of Auto Quasi Corresponding-period Equipment is developed with intelligent function. This equipment has formed the product and applied to many power stations with good effect. It has great value to be introduced widely.
