CONTROLLING METHOD FOR POWER OF WOUND-ROTOR INDUCTION MACHINE

摘要

PURPOSE:To maintain the stability of a power system by maintaining a target power value the maximum stability transmission power or lower determined by the relationship to a system at that time. CONSTITUTION:A switching signal 10 is input from a breaker 5A to a target power setter 6. A target power signal 11 is output in response to 1-channel service or 2-channel service time from the setter 6. A power controller 7 generates a control signal 13 to set the error between a power signal 12 and the signal 11 to zero, thereby controlling a frequency converter 9. The converter 9 controls the frequency, amplitude and position of a secondary current flowing in a secondary winding 2. Thus, even if a system state is varied, the target power value is set to the maximum stability transmission power or lower determined by the system at that time to always maintain the stability.
