This application relates to an energy-saving permanent magnet speed control system, including an adjustable speed prime mover, a permanent magnet speed governor, an automatic speed lock and an auxiliary speed governor; an adjustable speed prime mover, a permanent magnet speed governor and an automatic speed lock The permanent magnet speed governor is connected with the automatic speed lock and the auxiliary speed governor; the automatic speed lock is used to obtain the speed of the speed measuring device, and after linear compensation is performed by comparing the characteristic parameters stored in the automatic speed lock, the throttle is controlled Adjust the working state of the adjustable-speed prime mover, so that the adjustable-speed prime mover works at the preset optimal speed; the auxiliary governor is used to obtain the control command signal during work, and compare the characteristic parameters stored in the auxiliary governor for linear After compensation, control the electricity to adjust the output speed required by the permanent magnet governor. The above-mentioned system makes the speed-adjustable prime mover always work at the best efficiency without changing the rotating speed, ensures that the adjustable-speed prime mover always works at the best efficiency state, and achieves the energy-saving effect. The present application also relates to an energy-saving permanent magnet speed regulation method.
Description
technical field [0001] The present application relates to the technical field of prime movers, in particular to an energy-saving permanent magnet speed regulation system and method. Background technique [0002] Both the motor and the engine have a speed with the best efficiency, once it deviates from this speed, its working efficiency will decrease. Therefore, the application of permanent magnet speed control technology on the prime mover with constant speed has achieved significant energy saving effect. [0003] However, the energy-saving principle of permanent magnet speed regulation technology determines that it is only suitable for energy-saving speed regulation of constant speed prime mover. When the permanent magnet speed control technology is used for adjustable speed prime movers, such as DC motors, engines, etc., there are two speed control mechanisms, which cannot be used normally. [0004] Therefore, how to apply the permanent magnet speed control technology to...
