运用间接连接热水供暖系统实际动态数学模型,分析和比较换热站十种控制策略。研究发现当不考虑各换热站固有特性时,室内温度波动较大。采用当量室外温度及室内温度补偿控制策略时,本系统既可降低燃料消耗,也可提高热用户的热舒适度。创建基于供暖量和室内温度偏差的系统状态评价方法,并用于评价不同控制策略动态响应。结论中指出采用室内温度直接控制是最佳控制策略(控制策略10)。
Using the actual dynamic mathematical model of indirectly connected hot water heating system, ten control strategies of heat exchange station are analyzed and compared. The study found that when considering the inherent characteristics of each heat exchange station, the indoor temperature fluctuations. Equivalent outdoor temperature and indoor temperature compensation control strategy, the system can reduce fuel consumption, but also improve the thermal comfort of thermal users. Create a system state evaluation method based on heating volume and indoor temperature deviation and evaluate the dynamic response of different control strategies. The conclusions indicate that direct control of room temperature is the best control strategy (Control Strategy 10).
