摘要： 摘要：国内发电集团投资建设海外电厂时，热耗率谈判是购电协议(PPA)中非常重要一部分，直接影响投资收益。介绍了PPA谈判的流程及关键点，指出了煤价波动、燃煤高位热值、实际煤耗为燃料付款的影响因子，即热耗率、煤耗影响机组收益；通过分析特征工况及平衡点，进一步揭示了热耗率和煤耗对燃料付款的反作用。对比了印尼B，C电厂合同中热耗率及燃料付款的优、缺点，提出了设计、监造、施工、调试等过程关键点的控制，可为国内发电集团投资建设海外电厂提供参考。

Abstract: Abstract:When the domestic power generation groups invest in oversea power plant construction, the heat rate negotiation is an important part of the power purchase agreement (PPA), and it will influence on the investment income directly. The process flow and the key points of PPA negotiation were introduced. It was pointed out that the fluctuation of the coal price, the higher calorific value of the coal and the actual coal consumption are the factors influencing on the fuel payment, and the heat rate and the coal consumption will influence on the unit yield. According to the analysis on the typical working condition and the balance point, the counteractions of the heat rate and the coal consumption to the fuel payment were revealed further. The advantages and disadvantages of the heat rate and the fuel payment clauses in contracts of power plant B and power plant C in Indonesia were compared, and the control measures of the process key points of the design, the supervision of manufacturing, the construction and the commissioning were put forward, which provide reference for domestic power generation groups to invest in oversea power plant construction.
