能源综合利用效率是评价分布式能源系统热经济性的重要指标,相关文件关于该效率的计算方法因不区分冷热电能品位而受到质疑。对两个承担常见负荷、采用典型动力设备的天然气分布式能源系统进行分析,并将其与系统实际的能源产量比较,发现该效率值对系统热经济性的评估不具客观性与合理性,认为将该效率指标与经济杆杠相结合的做法或将分布式能源系统集成与运行设计引导至错误方向。
能源綜閤利用效率是評價分佈式能源繫統熱經濟性的重要指標,相關文件關于該效率的計算方法因不區分冷熱電能品位而受到質疑。對兩箇承擔常見負荷、採用典型動力設備的天然氣分佈式能源繫統進行分析,併將其與繫統實際的能源產量比較,髮現該效率值對繫統熱經濟性的評估不具客觀性與閤理性,認為將該效率指標與經濟桿槓相結閤的做法或將分佈式能源繫統集成與運行設計引導至錯誤方嚮。

Energy comprehensive utilization efficiency is an important evaluating index for evaluating thermal economy of distributed energy system.The existing relevant standards on calculating the efficiency without differentiating the energy grade of heat,cool and power is questioned.Analyses two distributed natural-gas energy systems adopting typical power equipment and bearing common loads,and compares their energy comprehensive utilization efficiency values with practical energy output.Finds out that the value of the efficiency is not objective and reasonable for evaluating the thermal economy of the system. Thinks that combining the efficiency index and economic leverage may lead the integration of distributed energy system and operation design to a wrong direction.
