热电联产电力调峰时供热系统的调节

热电联产电力调峰是解决供电峰谷差的重要途径,利用集中供热系统的热惯性是实施热电联产电力调峰的有效途径。在热电联产电力调峰运行模式下,热源供热量随电力负荷的变化而变化,供热系统内各点的供热介质温度及供暖室内温度也随之变化。为不影响供热质量,须控制供暖室内温度的波动幅度,此时热电联产电力调峰的幅度受热源的调节能力、集中供热系统的热惯性的影响。探讨了利用集中供热系统热惯性实施热电联产电力调峰运行模式时集中供热系统的4种运行调节方式。

Regulation of Heat-supply System during Electric Peak-shaving by Using CHP Plant

The electric peak-shaving by using CHP plant is a important way to minimize the difference between peak and valley loads of electricity supply,and using the thermal inertia of heat-supply system is a effective way to operate the CHP plant as an electric peak-shaving plant.Under the operation mode of using the CHP plant as an electric peak-shaving plant,the heat supply from heat source varies with electric load,and also the change takes place in temperature of heat-supply medium at different points in heat-supply system as well as in heating room temperature.In order to not influence heat-supply quality,the fluctuation amplitude of heating room temperature shall be controlled,while the amplitude of electric peak-shaving by using CHP plant is influenced by the regulation capacity of heat source and the thermal inertia of centralized heat-supply system A discussion is made on the 4 kinds of operation regulation modes of centralized heat-supply system when the operation mode of using the CHP plant as an electric peak-shaving plant is realized by using the thermal inertia of centralized heat-supply network.
