摘要

明确了热电厂电热解耦改造是为热电联产机组配置短期调峰热源的本质。从配置补偿调峰热源的角度，分析了储热补偿、电锅炉补偿、旁路补偿和低压缸切除补偿4种改造方案的适用场景、电热运行区间、供热成本、供热能力并建立数学模型。建立了改造后热电厂运行灵活性评价模型；结合算例分析了4种方案单独使用及组合使用时在不同电负荷场景下的灵活性提升效果。

Abstract

This paper shows that power-heat decoupling transformation of combined heat and power (CHP) plant is the essence of configuring short-term heat sources for CHP units. From the view of configuring compensation heat sources

applicable scenarios

feasible operation region

heating cost and heating capacity of four compensation strategies are analyzed

including heating storage

electric boiler

bypass compensation and low-pressure cylinder cut-off . The operation flexibility evaluation model of transformed CHP plant is established. Examples are given to analyze the flexibility improvement effects of the four strategies in different scenarios when they are used alone or in combination.
