  • Publication number: 20180347834
    Abstract: A method for controlling a photovoltaic air conditioning system. The method comprises: detecting a grid frequency (101); when the detected grid frequency is not equal to a pre-set frequency, calculating and obtaining a control parameter according to the detected grid frequency (102); and controlling a photovoltaic air conditioning by means of the calculated and obtained control parameter (103). Also disclosed is a photovoltaic air conditioning control device.

  • Publication number: 20180287557
    Abstract: A method, an apparatus, and a system for detecting the working state of a photovoltaic panel, and a photovoltaic electrical system are provided. The photovoltaic panel is arranged in a photovoltaic electrical system including a photovoltaic device and a control device. The photovoltaic device includes the photovoltaic panel and a modulator. The control device includes a demodulator. The photovoltaic device is connected to the control device via a direct current bus. The method includes: detecting the operating state of the photovoltaic panel to obtain a state parameter; modulating, through the modulator, the state parameter to obtain a modulated signal, and loading the modulated signal to the direct current bus; transmitting the modulated signal to the demodulator through the direct current bus. The demodulator demodulates the modulated signal to obtain the state parameter.
