摘　　要：集中供冷系统可通过水蓄冷方式提高能源利用率,降低能源成本,是目前集中供能站节能减排的主要举措之一。以某能源站为研究对象,提出了针对该能源站集中供冷系统在分时电价下的蓄冷运行方案,并模拟蓄冷工况下的运行策略,计算目前运行策略和蓄冷运行策略下的能源成本。结果显示:该能源站新增10万RT水蓄冷系统后,实现削峰填谷负荷615.2 kWh(约72%),每年节约电费约537万元,节省电费约56%。其中蓄冷罐投资费用约3770万元,投资回报期约7年。研究表明,在分时电价机制下,通过水蓄冷系统的削峰填谷策略可以显著提高集中供冷系统的经济效益,为能源站经济运行提供参考。The central cooling system can improve energy utilization and reduce energy costs through water cold storage,which is one of the main measures for energy conservation and emission reduction of central energy supply stations.Taking an energy station as the research object,a cold storage operation scheme for the central cooling system of the energy station under the time-of-use electricity price was proposed,and the operation strategy under the cold storage condition was simulated,and the energy cost under the current operation strategy and the cold storage operation strategy was calculated.The results show that after the addition of 100000 RT water cold storage system to the energy station,the peak load of peak shaving and valley filling is 615.2 kWh(about 72%),saving about 5.37 million yuan and 56%of electricity costs per year.Among them,the investment cost of the cold storage tank is about 37.7 million yuan,and the return on investment period is about seven years.The results show that under the time-of-use electricity price mechanism,the peak shaving and valley filling strategy of the water cold storage system can significantly improve the economic benefits of the central cooling system,and provide a reference for the economic operation of the energy station.
