摘要:

针对我国北方寒冷地区冬季供暖期电网调峰能力严重不足的现状,以研究大型供热机组供暖期调峰能力为目的,根据等效热降理论得出供热机组调峰能力理论模型以此为基础本文采用现场试验核定的方法确定电网内每台供热机组不同抽汽供热量时机组所对应的调峰高限负荷和调峰低限负荷采用多项式回归方法建立相应的调峰能力实际应用模型,为大型供热机组深度参与电网消纳风电提供理论依据和技术支持。在吉林省电网的应用也证明了模型的正确性和有效性。

In allusion to the serious capability inadequacy of peak-load regulation of power network during the heating seasons in north China, by making use of the basic theory of equivalent enthalpy drop method, a theoretical model is derived for the peak-load regulation capacity from large units during the heating period. Then based on it, the peak-load regulation capacity minimal load and maximal load of every large heating unit in different heating loads were obtained by field tests and the application models were established by polynomial fitting method which supplied theoretical basis and technical support for the large heating units deeply involved in peak regulation of power network. The accuracy and validity of the method are confirmed by the application in Jilinpower grid.
