Abstract: A new type automatic quasi2synchronization device based on double microp rocessors is introduced, it is made up of two independent control unit, one control unit accomp lishes the forecast of synchronization and regulates the generator’s voltage and frequency , another control unit perform s the blocking function. Constant time lead p rin2 cip le is used to forecast the synchronization time, P ID 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 MM I, it has RS485、 CAN、Ethernet communication interface. Key words: automa tic qua si2synchron iza tion; double m icroprocessors; ethernet
