Distributed type combined cycle generator set cooperative peak conditioning and heat supplying system and method

Abstract

The invention relates to the technical field of combined cycle electricity generation, heat supplying and control, in particular to a distributed type combined cycle generator set cooperative peak conditioning and heat supplying system and method. The system comprises a first extraction condensing type adjustable heat-supplying steam turbine generator set, a second extraction condensing type adjustable heat-supplying steam turbine generator set, a back pressure type heat-supplying steam turbine generator set, a high-pressure steam header, a low-pressure steam header, a waste heat boiler, a heat user, a waste heat boiler low-pressure superheater coming piping system and a waste heat boiler high-pressure superheater coming piping system. According to the distributed type combined cycle generator set cooperative peak conditioning and heat supplying system and method, outlet steam of a plurality of waste heat boiler high-pressure superheaters is collected into the high-pressure steam header, the outlet steam of a plurality of waste heat boiler low-pressure superheaters is collected into the low-pressure steam header, by means of this technical method adopting piping-main scheme, the flexibility of running switching between the extraction condensing type steam turbine generator sets and the back pressure type heat-supplying steam turbine generator set is improved, and electrical load and thermal load can be switched according to requirements in real time.

Description

technical field [0001] The invention relates to the technical field of combined cycle power generation, heat supply and control, in particular to a system and method for coordinated peak regulation and heat supply of distributed combined cycle generator sets. Background technique [0002] With the increase of new wind power installed capacity in the grid, due to the intermittent and uncertain characteristics of wind power, the output of wind turbines is unstable and cannot provide stable power supply for the urban grid. The traditional condensing heating unit has high power generation. The heat supply capacity has a lot to do with it. However, when the heat supply does not change synchronously after the power supply changes, there is a conflict between the power supply and the heat supply. Contents of the invention [0003] In order to solve the above problems, enhance the power supply support of the urban power grid, optimize the energy structure, improve the operating co...
