Snow melting system of photovoltaic power station

Abstract

The invention discloses a snow melting system of a photovoltaic power station, which comprises an accumulated snow sensing unit, a snow melting control unit, a snow melting unit, a water storage tank and a hazard processing unit, wherein the accumulated snow sensing unit is used for sensing the accumulated snow information, the snow melting control unit is used for receiving the accumulated snow information and controlling snow melting processing, the snow melting unit is used for executing snow melting processing, and the water storage tank is used for storing the melted snow water. According to the invention, through the central heating manner, the snow melting system reduces investment in a heater, improves the efficiency of the heater, and guarantees the safety and reliability of the system; the complementary multiple modes enable the snow melting operation of the photovoltaic power station to be reliable and flexible, and the hazards are processed before the snow water is discharged, so that pollution to the local land and water resources is effectively avoided.

Description

technical field [0001] The invention belongs to the field of photovoltaic new energy, specifically relates to the design, construction, operation and maintenance of photovoltaic power stations, mechanical automation equipment and other industries, and particularly relates to an effective, controllable and low-cost snow melting system for photovoltaic power stations. Background technique [0002] With the increasingly serious problems of environmental pollution, climate warming and energy crisis, countries all over the world are scrambling to develop renewable energy. According to statistics, by the end of 2011, the cumulative installed capacity of solar photovoltaic in Germany had reached 25G watts, and by the first half of 2012 , Germany's total photovoltaic power generation capacity reached 14.7 billion kWh, accounting for 4.5% of its total electricity consumption. [0003] According to statistics, the total global photovoltaic installed capacity is expected to increase fr...

The decline in power generation of photovoltaic power stations will undoubtedly bring significant losses to photovoltaic power station enterprises

[0006] In addition, with the deterioration of the global climate, there have been frequent abnormal disasters in recent years, such as the once-in-a-century ice disaster in Hunan and Guizhou in January 2008, which not only directly affects the power generation of photovoltaic power stations, but also has a negative impact on photovoltaic power stations. The equipment and structure bring about devastating damage, which directly leads to the rupture of photovoltaic modules and the collapse of brackets
