每套区域供热系统都需要有一种总控手段,这种总控手段要有较大的灵活性,並能在任何情况下以最经济的方式利用热网系统和热源装置。目前,区域供热系统上普遍存在着分散的泵组的运行问题,存在着多热源的问题,如:热电厂、烧油或烧固体燃料的热水厂、垃圾焚烧厂、余热厂、热泵、太阳能供热厂和积蓄器等等,这样总控手段就显得更为必要了。这种控制手段必须能随着燃料价格和每年每日热需比量的变化而变化,必须能随着区域供热系统的发展,易于不断修改,迅速适应新情况。下面介绍 AF—能源咨询公司研究的区域供热用控制、协调运
Each district heating system requires an overall control method. This total control method requires greater flexibility and can utilize the heat grid system and the heat source device in the most economical manner in any case. At present, there are widespread problems with the operation of decentralized pump sets in district heating systems. There are multiple heat source problems such as: thermal power plants, hot oil plants that burn oil or burn solid fuels, waste incineration plants, waste heat plants, heat pumps, and solar energy Heating plants and accumulators, etc., so that the total control means is even more necessary. This control method must be able to change with the fuel price and the annual daily heat demand ratio, and it must be able to be continuously modified to adapt to new situations as the district heating system develops. The following describes the control and coordination of regional heating research conducted by AF-Energy Consulting.
