摘要
介绍一种新型双微机自动同期装置,它含有两块独立的控制单元,一块完成同期点的预报及发电机电压、频率的调节,另一块完成同期闭锁功能。该装置利用恒定导前时间同期原理预报同期点,采用PID控制方法调节发电机电压和频率,具有录波及数据存储功能和友好的人机界面,以及标准的RS-485、CAN、以太网通信接口。
A new type automatic quasi-synchronization device based on double microprocessors is introduced, it is made up of two independent control unit, one control unit accomplishes the forecast of synchronization and regulates the generator＇ s voltage and frequency , another control unit performs the blocking function. Constant time lead principle is used to forecast the synchronization time, PID control method is used to regulate the generator＇ s voltage and frequency, it has recording function and data storage function and a set of friendly designed MMI, it has RS485, CAN,Ethernet communication interface
