Bài giảng Tối ưu hóa vận hành hệ thống điện - Chapter 8: Control Of Generation - Võ Ngọc Điều

(Bản scan)

The isochronous governor • to force frequency errors to zero requires the use of an

integration of the speed error • the isochronous governor can not be used when two or more generators are electrically connected to the same system • fighting between generator governors for system frequency

• problems with load distribution between generators A load reference control provides settings for both the frequency and the desired output power • a new input, the load reference signal, controls the desired

power output • feedback loop contains a gain R that determines a speed-droop

characteristic
