GE通用电气 IS210AEPSG1AFC 电路板模块 MARK VI系统

系统特点

试验台系统的电源控制部分采用功率单元结构形式，控制系统为国际流行的一块大板结构，控制电路实现了集成化、数字化。

整个系统的继电控制采用了一台小PLC(ProgrammableLogicController)，具有故障自诊断与保护功能，继电操作与整机保护功能完善。直流电机调速部分采用速度、电流、电压三环控制系统。

通过与直流电机同轴相连接的光电编码器输出的数字信号作为速度反馈信号以保证整机的调速精度，从而保证了同步发电机输出电压的频率精度达到异步电机试验所要求的电源频率的精度要求。

增加电压内环是为了保证系统在低速段运行的稳定性，从而保证了低频段的频率精度，为交流变频电机的试验创造了良好的试验条件。 

System characteristics

The power control part of the test bench system adopts the form of power unit structure, the control system is a large board structure which is popular in the world, and the control circuit is integrated and digitized.

The relay control of the whole system (ProgrammableLogicController), adopted a small PLC has fault self diagnosis and protection function, relay operation and perfect protection function. Dc motor speed regulation part adopts speed, current, voltage three-loop control system.

The digital signal output by the photoelectric encoder coaxially connected with the DC motor is used as the speed feedback signal to ensure the speed regulation accuracy of the whole machine, so as to ensure that the frequency accuracy of the output voltage of the synchronous generator can meet the precision requirements of the power supply frequency required by the induction motor test.

The increase of the voltage inner ring is to ensure the stability of the system in the low speed section, so as to ensure the frequency accuracy of the low frequency band, and create a good test condition for the test of the AC variable frequency motor.
