FCB operation method of garbage power plant

Abstract

The invention discloses an FCB operation method of a garbage power plant. The FCB operation method comprises the following steps: 1) a garbage power plant unit is set according to FCB operation requirements; (2) when a power distribution network fault occurs, the unit splitting control device issues a generator tripping instruction to enter an FCB running state; (3) the garbage power plant unit enters an FCB operation state after receiving the FCB starting signal; and 4) after the power grid fault is eliminated, isolated island operation is performed, and grid connectionis performed again. On one hand, when a power grid connected with the garbage power plant breaks down, all external power supply loads are instantly thrown away to be separated from an external power grid, a unit does not stop, so that self power utilization of the power plant is maintained, and after the fault of the power grid is eliminated, the unit can be provided with a plant power load, rapidly and effectively connected with the external power grid and supply power to the system; and on the other hand, the boiler does not flame out, and the livelihood problem of timely treatment of household garbage is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of garbage power generation, and in particular relates to a FCB operation method of a garbage power plant. Background technique [0002] With the rapid development of the economy and society, the country vigorously advocates clean, green and environmentally friendly power generation. For traditional coal power plants, waste-to-energy power plants take into account the two major livelihood issues of power generation and domestic waste disposal. Therefore, the high reliability of the unit and continuous Operation puts forward higher requirements. However, due to the limited capacity of waste-to-energy plants, waste-to-energy plants are mainly used as power sources at the load end of the distribution network. The power supply reliability of the distribution network at the load side is weaker than that of the traditional main power grid, and power grid accidents are prone to occur. When the power plant unit is ...

AI Technical Summary

Problems solved by technology

Because the load-side distribution network is prone to failure, when the load-side distribution network connected to the waste-to-energy plant fails, on the one hand, it will cause drastic changes in the parameters of the unit, resulting in abnormal shutdown of the unit, damage to the unit equipment, and restarting the unit Consumes a lot of fuel, causing huge economic losses; on the other hand, it is easy to cause people's livelihood problems that the garbage cannot be disposed of in time due to the flameout of the boiler
