Heat supply system and intelligent control method for dual load peak regulation of cogeneration units

Abstract

The invention relates to a heat supply system for cogeneration unit double-load peak shaving and an intelligent control method. The heat supply system structurally comprises a remote control platform, a thermoelectric unit system, a steam heat storage system, an electric energy heat storage system, a heating network system and a power grid. The thermoelectric unit system comprises a turbine and a power generator which are matched. The steam heat storage system comprises a steam-water heat exchanger and a first hot water heat storage tank. The electric energy heat storage system comprises a hot water electric heater and a second hot water heat storage tank. The heating network system comprises an initial station, a primary network heat supply pipe and a heat user. Based on a heat storage peak shaving system, the heat supply system capable of achieving electric power peak shaving and also conducting peak clipping and valley filling on thermal loads and the intelligent control method are reasonably designed, electric loads of a thermal power unit can be deeply reduced, electric power peak shaving is conducted, meanwhile, due to the combination of the heat storage systems, the heat supply quality of residents is ensured, and high practical application value is achieved.

Description

technical field [0001] The invention relates to an energy regulation system and method, in particular to a heat supply system and an intelligent control method for dual-load peak regulation of cogeneration units. Background technique [0002] At present, my country's policies are gradually emphasizing the promotion of new energy sources and reducing the proportion of thermal power units. By the end of 2012, my country had installed wind power capacity of 44.8GW. However, wind power has strong randomness, intermittency, uncontrollability and anti-peaking characteristics, which gradually increases the difficulty of thermal power units in power grid peaking. In order to effectively consume new energy resources, the country has gradually increased the policy requirements for peak regulation of thermal power units. Requirements: (1) Improve the consumption space of clean energy: give full play to the decisive role of the market in resource allocation, mobilize the peak-shaving ...

Problems solved by technology

Existing peak regulation focuses on single peak regulation. For example, Chinese patent CN1093791A discloses a peak regulation system that stores heat for heat storage tanks during power grid trough times. Correlation between electric energy, there is waste or insufficient heat supply during peak regulation of electric power, so it is necessary to provide a heating system that can not only guarantee heat supply, but also make full use of heat energy and electric energy
