Radio frequency-based solar energy and wind energy complementary power supply system and working method thereof

Abstract

The present invention discloses a radio frequency-based solar energy and wind energy complementary power supply system and a working method thereof. The radio frequency-based solar energy and wind energy complementary power supply system comprises a monitoring management center, an RF network and a plurality of peasant household monitoring nodes, the monitoring management center comprises an industrial control PC and an RF communication module which exchange the data via the serial connection, and each peasant household monitoring node comprises a solar cell panel, a wind turbine, a wind and photovoltaic complementary control unit, an electric power main control unit and an RF communication module. The output ends of the solar cell panels and the wind turbines are connected with the inputends of the wind and photovoltaic complementary control units, the wind and photovoltaic complementary control units convert the DC outputted by the solar cell panels and the AC outputted by the windturbines into the DC to output to the electric power main control units, and a public power grid is connected with the power supply input ends of the electric power main control units. The RF communication modules and the electric power main control units establish the bidirectional communication connection, and the monitoring management center and the peasant household monitoring nodes respectively utilize the respective RF communication modules to establish the communication connection via the RF network.

Description

technical field [0001] The present invention relates to a power supply system, which comprehensively applies wireless communication technology, network technology and automatic control principle, is the application of clean energy and building energy-saving technology in rural buildings, and specifically relates to a solar and wind energy complementary power supply system based on wireless radio frequency and its working methods. Background technique [0002] At present, rural residences are basically in a state of spontaneous construction without architectural design, failing to fully consider environmental factors such as climate, orientation, and ventilation, and failing to make good use of renewable energy. On the other hand, rural residences still use decentralized heating methods, and the heating energy consumption is seriously wasted. Rural residential exterior walls, roofs, doors and windows, etc. still use conventional practices. The insulation performance of the b...

[0002] At present, rural residences are basically in a state of spontaneous construction without architectural design, failing to fully consider climate, orientation, ventilation and other environmental factors, and not making good use of renewable energy

On the other hand, rural residences still use decentralized heating methods, and the heating energy consumption is seriously wasted

Rural residential exterior walls, roofs, doors and windows, etc. still adopt conventional practices, and the building enclosure structure has poor thermal insulation performance, and the heat transfer coefficient of exterior walls and roofs greatly exceeds the limit value of building energy-saving design standards, resulting in serious waste of heating energy consumption
