热电联产机组协同改造及其调峰与供热能力分析
Analysis of Modification of Cogeneration Units and Its Peak Regulation and Heat Supply Capacity
摘要
Abstract
Through the collaborative transformation of two 135 MW units and two 330 MW units of a power plant with high backpressure and low-pressure cylinder cutting,which operating in multiple heating modes,the performance indexes of four units in the heating period are obtained from the performance test after transformation,and the analysis shows that the peaking capacity of the whole unit in the heating period is 504.39 MW,which is 9.39 MW higher than the one before the transformation,and the minimum load is 39.27 MW lower.While the heating capacity is increased,the peak shifting capacity and the scheduling flexibility of low load are significantly improved.In view of the fact that the four units of the power plant are equipped with two heat supply pipelines in the east and west respectively,based on the operating characteristics and energy consumption indexes of the units,the collaborative operation mode and the distribution of electricity and heat loads under multiple heat supply modes are optimized.Under the condition that the thermal load of the whole plant and the total steam intake of the units remaining unchanged,the capacity of the four units to carry electric load increases by 25～40 MW.关键词
