单元式热力发电机组能耗率评价方法研究

Research on Energy Consumption Evaluation Method of Unit Type Thermal Power Generating

常规热力机组性能计算方法采集数据量庞大、计算过程繁杂,往往不同单位试验得出的经济指标相差比较大,对机组经济指标准确度判断误导性比较大。采用单元式能量平衡评价方法进行机组性能核算时,可以大幅减少数据采集量和计算步骤,更贴近实际的机组经济指标。

According to the current energy consumption evaluation of unit thermal power generating units,the anti-balance method is used which has the problems of taking many test data,large cumulative error,large deviation of test results and so on.It adopts a method of unit energy consumption balance for thermal power generating.This method has less test data and less cumulative error.It can calculate the energy consumption index of a single generating unit or even the whole power plant simply and accurately.
