Abstract

The invention discloses a photovoltaic air conditioner frequency converter electric energy controller. The controller comprises a sampling circuit module, a data processing module and a storage module, and is characterized in that the sampling circuit module is used for acquiring electric signals of a photovoltaic system side and a motor load side inside a photovoltaic air conditioner frequency converter and electric signals of a power grid side outside the photovoltaic air conditioner frequency converter according to a predetermined cycle; the data processing module is used for carrying out calculation for predetermined parameters according to the electric signals acquired by the sampling circuit module; and the storage module is used for storing data acquired by calculation of the data processing module. The photovoltaic air conditioner frequency converter electric energy controller provided by the embodiment of the invention reduces the electric energy measurement cost of the frequency converter, simplifies an external interface of a frequency converter controller, realizes recording for intermediate process quantities of a power generation mode and a power consumption mode of the photovoltaic air conditioner frequency converter, and forms a set of unified electric energy calculation and management system. The invention further discloses a photovoltaic air conditioner frequency converter electric energy control system.

Description

technical field [0001] The invention relates to the field of power electronics technology, in particular to a power controller and control system for a photovoltaic air conditioner inverter. Background technique [0002] With the increasingly tense world energy and the rapid development of power electronics technology, the demand for photovoltaic air-conditioning inverters is increasing, and the requirements for the control system of photovoltaic air-conditioning inverters are also becoming more and more diverse, including photovoltaic air-conditioning inverters Power controller and control system. [0003] Photovoltaic air conditioner inverter is an inverter that integrates two functions of photovoltaic system and air conditioner power supply, including photovoltaic system and motor load. The photovoltaic air conditioning control system controls the free flow of energy among the photovoltaic system, motor load and grid. The flow of electric energy from the photovoltaic sy...
