This invention relates to a technical method and scheme for idle component of power system to do work instead of reactive compensation by limiting the power-utiligation angle of the equipment within the front 90 degree range of each half-period to make the power-utilization angle of an equipment coincide with the idle component angle of power system. The applied energy is the idle component of the power system. When the idle component is not enough, the power source replenishes the energy. The equipments surpass the function of simple doing work and also improve the work doing state of the power system at the time finishing the task of operation.
Description
(1) Technical field [0001] The invention belongs to the comprehensive energy-saving technology of electric power system. This technology can be applied to improve the power factor of the power system, manufacture energy-saving power supply and energy-saving electrical equipment. (2) Technical background [0002] At present, the method of reactive power compensation is adopted for the reactive components of the power system. Due to the limitations of existing technologies, the reactive components of the power system have not been completely balanced and effectively utilized. The resulting energy Losses account for more than 10% of the total energy in a power system. [0003] At present, there is no electrical equipment that specifically uses the reactive component of the power system to do work. [0004] At present, there is no new technology that can replace the current method of reactive power compensation. (3) Contents of the invention [0005] The technical problem t...
