基于微燃机的冷热电供能系统经济性分析
Economic analysis on CCHP system based on micro-gas-turbine
摘要：
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。
Abstract：
Taking an actual hotel as energy supply example, proposes a time-divided joint energy supply mode consisting of CCHP distributed energy supply system based on micro-gas-turbine and the original energy supply system. When the price difference of peak and valley electricity is large, the joint mode is more economic. According to the hotel simulation load and micro-gas-turbine minimum load rate, optimizes the annual electricity generation capacity, cooling and heating capacity of micro-gas-turbine CCHP system. Analyses the influences of fuel price and the investment cost on the payback period of micro-gas-turbine system, and verifies the economic, energy saving and environmental properties of the micro-gas-turbine system.
