Abstract

The invention discloses a wind-solar electricity generation system used on an expressway. The wind-solar electricity generation system is composed of a solar photovoltaic array, a wind turbine, a permanent magnet generator, an electric wire, a power grid, a load and the like. When sunlight shines on the solar photovoltaic array, the solar photovoltaic array converts light energy into electric energy so as to generate electricity; when vehicles running on the expressway pass through isolation zones, wind power is generated to drive the generator to generate electricity. According to the working mode, the permanent magnet generator outputs an alternating current, the alternating current becomes a direct current after being rectified, and the direct current from the permanent magnet generator and a direct current from the photovoltaic array charge a storage battery under the control of a controller. The controller not only controls the permanent magnet generator and the solar photovoltaic array to charge the storage battery but also manages charging of the storage battery for the load. A variable speed and constant frequency control model is adopted for the wind-solar electricity generation system, the permanent magnet generator is adopted as an engine, and therefore stable and continuous electric energy can be provided, and power frequency alternating current 220V electric energy and power frequency alternating current 380V electric energy can be provided.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a wind power generation system used on expressways. Background technique [0002] In some areas with rich wind resources and sufficient sunlight, there are often relatively or very remote areas, which are often far away from towns, and also very far away from power stations and power distribution units. There are no hydropower resources available here, nor mineral resources (oil, coal and natural gas, etc.), in order to provide power to these areas, the government often has to lay very long and very complicated transmission lines, which wastes a lot of financial resources. And its power consumption is not large, and the amount that may be consumed on the transmission line will account for a non-negligible part of its usage. Transmitting electric energy to these areas is a matter of loss outweighing the gain, requiring a large upfront investment (long transmis...
