以某酒店为供能对象,提出了微燃机分布式能源系统与酒店原有供能方式分时段联合供能的模式,当峰谷电价差较大时,此联供模式较为经济。根据酒店模拟预测负荷和微燃机最低负荷率,优化了微燃机系统的全年发电量、制冷量、制热量。分析了燃料价格和微燃机系统投资对回收年限的影响,验证了微燃机系统的经济性和节能环保性。
Taking a hotel as energy supply target, this paper puts forward the mode that the distributed energy system of the micro gas turbine and the original energy supply mode of the hotel are co-energized at different time points. When the peak-valley electricity price difference is large, the combined mode is more economical. According to the simulated load of the hotel and the minimum load rate of the micro-engine, the annual power generation, cooling capacity and heating capacity of the micro-combustion engine system are optimized. The influence of fuel price and the investment of micro-gas turbine system on the recovery period is analyzed, and the economy, energy conservation and environmental protection of the micro-gas turbine system are verified.
