Abstract

Provided is a multi-unit turbine steam flow real-time distributing method based on a main pipe scheme. The historical steady-state data of piping-main scheme units are processed through the data mining technology when each turbine independently runs, a power and steam inlet hot flow function relationship calculating model of each turbine is established, when all the turbines of the units simultaneously run, inputting the loads, main pipe steam pressure and steam temperature data, collected in real time, of all the turbines to the calculating model, outputting the steam inlet hot flow, corresponding to current control boundary conditions, of all the turbines through the calculating model so as to calculate steam flow required to be distributed to all the turbines, and considering the influences of changes of all the turbines along with the running time on the characteristic changes of the turbines through a regular calculating model renewing method.

Description

technical field

[0001] The invention belongs to the technical field of real-time steam flow distribution of steam turbines, and in particular relates to a method for real-time distribution of steam flow of multi-unit steam turbines based on master control. Background technique

[0002] The main pipe operation system refers to the steam generated by all the boilers in the power plant is collectively led to one steam main pipe, and then the steam main pipe is respectively guided to each steam turbine and other operation systems that need to use steam. Generally, it is only used in low-parameter power plants. this kind of system.

[0003] Power plants and thermal power plants with a unit capacity of less than 60MW in my country, such as cogeneration and heating power generation units built by many large industrial enterprises to meet their own electricity and steam needs, centralized heating units in northern cities in my country, and garbage power plants etc., the main steam s...
