The invention provides an SOFC power generation system and a control method of the SOFC power generation system. The invention discloses an SOFC power generation system, relates to the technical fieldof electricians, and aims at solving the technical problem that when the SOFC power generation system comprises a plurality of SOFC power generation units, the structure and control process of the SOFC power generation system are complex due to the fact that independent battery compensation devices are arranged for the plurality of SOFC power generation units. The SOFC power generation system provided by the invention comprises an SOFC power generation subsystem, a battery compensation subsystem and a controller which is respectively coupled with the SOFC power generation subsystem and the battery compensation subsystem, wherein the SOFC power generation subsystem and the battery compensation subsystem are jointly connected to an alternating current bus to realize grid connection, and theSOFC power generation subsystem provides output power for a power grid through a plurality of SOFC power generation units; and the controller controls the battery compensation subsystem to provide power compensation for the power grid according to the output power of the SOFC power generation subsystem and the instruction power of the SOFC power generation system. The method is used for simplifying the structure of the SOFC power generation system and the control process of the SOFC power generation system while ensuring that the SOFC power generation system realizes quick dynamic response.
Description
technical field [0001] The invention relates to the field of electrical technology, in particular to a SOFC power generation system and a control method for the SOFC power generation system. Background technique [0002] Oxide fuel cell SOFC is a power generation device that uses electrochemical power generation. It has high power generation efficiency. At the same time, because most of the power generation products are water and carbon dioxide, it causes less pollution to the environment and has great development prospects in clean energy. [0003] At present, due to the complex mass and heat transfer process involved in SOFC power generation, SOFC-based power generation usually has the problem of slow dynamic response. Or it's hard to fast track load charge changes while islanding, etc. In order to solve the above problems, at present, devices such as batteries with fast response characteristics connected to the SOFC are installed on the side of the SOFC as the battery co...
