Abstract

The invention discloses a wind, light and heat energy storage complementary power generation system, and belongs to the technical field of electric power. The system comprises a wind generator, a photovoltaic cell panel, an alternating-current voltage stabilizing circuit, an inverter, a lead-carbon cell, a compensating circuit, a molten salt heating system, a solar collector group, a molten salt storage container and a conventional turbine generator. The system solves the technical problem that fluctuation of photovoltaic and wind power generation power needs to be compensated by stored heat energy. The system is the most suitable for complementary running with a light and heat solar collector heating molten salt heat storage type power plant, 24*7 stable power output can be realized aftera large-scale photovoltaic and wind power station uses molten salt exceeding 8 hours for heat storage, and a molten salt heat storage mode is low in cost and environmentally friendly as compared withan existing energy storage mode.

Description

technical field [0001] The invention belongs to the field of electric power technology, in particular to a wind, light and thermal energy storage complementary power generation system. Background technique [0002] Sunshine and wind are completely uncontrollable and unpredictable. In addition to the complete failure of the photovoltaic power station after sunset, there are also occasional clouds that cause fluctuations in the power generation of the photovoltaic power station. Energy fluctuates. [0003] When the power fluctuation of photovoltaic and wind power generation reaches a certain level, it will cause obvious fluctuations in the grid voltage, which will destroy the voltage stability of the power system. The stability of voltage is an important consideration in power system operation. [0004] At present, the most commonly used method is to store electricity in batteries, but with the different materials used in batteries, the extended problems are also different. ...
