The invention relates to an air source heat pump reactive power compensation control system and method. The electric parameter instrument collects the three-phase apparent power and power factor of the air source heat pump, and PLC respectively calculates the fan during the heat pump operation process according to the three-phase apparent power and power factor. The real-time capacitance compensation amount after operation and compressor operation and the real-time capacitance compensation amount after the compressor stops step by step during the heat pump stop process, according to the real-time capacitance compensation amount, the capacitor switcher is controlled to compensate the corresponding capacitance compensation amount in the three-phase power capacitor Into the main circuit of the heat pump, real-time reactive power compensation for the heat pump is realized, the reactive power loss of the heat pump is reduced, and the energy-saving performance of the heat pump is further improved.
Description
technical field [0001] The invention relates to the technical field of reactive power compensation control, in particular to an air source heat pump reactive power compensation control system and method. Background technique [0002] In the actual operation of the heat pump process, due to the crossing of the four seasons and the temperature of the outlet water rising from low temperature to high temperature, the range of operating conditions of the compressor is too large, resulting in a very low power factor of the compressor in a certain working condition, and the reactive power in the initial operation stage of the heat pump. The loss is greater than or equal to 40%, even if the heat pump runs to the demand condition, the reactive power loss is also 20%. [0003] Air source heat pump is an energy-saving technical product, which has been widely promoted and applied. However, during the test, it was found that the power factor of the host of the air source heat pump was b...
