Embodiment Construction

[0026] The invention relates to a method and system for scheduling online loads of heating units. Based on the on-line monitoring technology of heat-supplied units, the minimum power generation load of each heating unit is determined through the heat supply capacity of the heat-supply units. The prediction method of power and quantity is realized, and by controlling the minimum power generation load of the heating unit, the pressure of low-load peak-shaving of the power grid during the heating period is effectively relieved. The method steps are as follows:

[0027] 1. Real-time online monitoring of relevant parameters of the heating unit. The data comes from the on-site DCS system and additional monitoring points. It is mainly divided into two aspects, one is the heating network parameters, and the other is the unit parameters. These parameters are transmitted to the monitoring center of the power grid dispatching department to monitor the operating status and operating mod...

Abstract

The invention provides a scheduling method of a heat supply unit online load and a system. The scheduling method and the system are suitable for implementation of reasonable scheduling of a heat supply unit in a heating period. According to the method of the invention, based on the combination of real-time monitored data of parameters of the heat supply unit in a power grid, each heat supply index of a computer group, steam turbine variable working condition method and the actual operation status of the unit, an ordering power by heat mathematic model can be obtained, and therefore, power grid scheduling personnel can perform scheduling through adopting a minimum load mode, a load fast decreasing/increasing mode, and an energy-saving mode, and a basis can be provided for decision making in heat supply unit scheduling; according to weather forecast released by the meteorological department, and based on the combination of regression analysis results of historical data of the heat supply unit, weather, temperature and wind can be applied to heat supply quantity prediction; and according to predicted heat supply quantity, and based on the ordering power by heat mathematic model, electric power and electric quantity of a next day or a next month of the unit can be predicted.

Description

technical field [0001] The invention relates to a method and system for scheduling online loads of heating units, which are mainly used in load scheduling, electric power and electricity forecasting of heating units in thermal power plants, and solve the problem of peak regulation of power grids during the heating period, thereby maximizing the acceptance of wind power, The purpose of clean energy such as nuclear power is to reduce energy consumption and reduce pollutant emissions. Background technique [0002] At present, cogeneration units are mostly used in northern my country to provide heating and heating in winter. When the capacity of heating units accounts for a large proportion of the entire power grid, since the power dispatching department cannot implement the online heating status of each unit, in order to ensure reliable heating The heating unit has a large power generation load margin, which brings difficulty to the power grid's low-load peak regulation. [000...
