| Abstract: | Cascade speed regulation is an energy-saving style by feeding back the slip power to power system. Double closed loop is adopted to improve controlling system static and dynamic performance for requirement of working field. Speed and current regulator parameter of cascade speed regulation system of double closed loop under sub-synchronous speed is designed by using scheme of engineering design,then adjusted and optimized by experiment. System performance can be fulfilled and design period can be shortened by using this scheme. It is proved that the scheme is scientific and practicable in practice. |
