|  DSP microcomputer excitation device applicable for the capacity is less than or equal to 1MW~*0MW of hydropower synchronous generator excitation systems and the capacity is less than or equal to 1MW~*0MW of steam synchronous generaor excitation system. Characteristics of PLC DSP microcomputer excitation device 1. Rectifier circuit use the separated type rectifier module, all control single bridge, the main bridge and three-phase no phase sequence phase position requirements; 2. Use DSP series ECA-IV type programmable microcomputer excitation control regulator; 3. The kernel of controller use the **-bit DSP chip imported from the United States, AC/DC power supply, high reliability and speed, AC sampling, complete function; 4. Man-machine interface use graphic operating terminal, display and set on the 5.7 inch large screen LCD Chinesization touch screen; 5. Use vacuum heat pipe for heat dissipation with temperature monitor and control and back fan; 6.With standard RS**5 serial interface and CAN bus, with four remote controls function(remote measuring, remote signalling, remote regulating and remote control); 7. High adjustment precision, stable operation with good static and dynamic characteristics; 8. Easy operation and maintenance; 9.The entire screen adopts modularization, unitization, drawer type design. Main function of DSP microcomputer excitation device 1. Constant pressure regulating function according to the voltage deviation of generator terminal. 2. Constant flow regulating function with exciting current as feedback. 3. Constant COSΦ regulating function with power factor as feedback. 4. Constant pressure regulating, constant flow regulating, constant COSΦ regulating functions can be arbitrarily switched without disturbance. 5.Over-excitation limit. 6.Voltage/frequency(V/F) limit. 7.Under-excitation limit. 8.No-load overvoltage protect. 9.PT open circuit protection. *0.Dual computer hot standby. (optional) *1.Multi-bridge automatically current-sharing. *2.Truly achieve AC sampling. |
