Abstract

The invention relates to the technical field of power transmission, in particular to an optical storage micro-grid flexible networking system for a thermal power plant. The optical storage micro-grid flexible networking system for the thermal power plant comprises a thermal power plant unit which comprises a 6kV station bus and is used for performing power transmission on a power grid system; comprising a photovoltaic-energy storage-low-voltage electrical load micro-grid unit of a 400V integrated energy bus and is used for performing power transmission on the thermal power plant unit through a soft switching unit and a voltage transformation unit; and the high-voltage side of the soft switch unit transformation unit is connected to a 6kV station service bus, and the low-voltage side of the soft switch unit transformation unit is connected to a 400V comprehensive energy bus, and is used for providing a power transmission channel when the thermal power plant unit and the photovoltaic-energy storage-low-voltage electrical load micro-grid unit carry out power transmission. According to the technical scheme, the optical storage micro-grid flexible networking system for the thermal power plant is low in equipment failure rate, flexible in control mode and high in power supply reliability.

Description

technical field [0001] The present application relates to the technical field of power transmission, and in particular, to a flexible networking system for an optical storage microgrid for thermal power plants. Background technique [0002] With the development of science and technology, thermal power plants are transforming and upgrading towards comprehensive energy load supply enterprises. In the related art, when a photovoltaic system is incorporated into a high-voltage busbar system for thermal power plants as a type of load source, it is necessary to select a corresponding access scheme according to different access capacities. These schemes have a common point, that is, both the power supply and the load are connected to the high-voltage busbar system for thermal power plants. But this will exceed the original design capacity of the bus, and then need to expand the interval. In addition, the short-circuit current exceeds the limit after the large-capacity load is con...
