【摘要】：电力电量平衡计算对电力系统中设计电站的今后运行和在线运行电站的负荷分配、备用容量配置具有重要意义,同时能为合理利用水能资源以及化石能源、减少资源浪费、环保减排起到指导作用。针对电力系统年、月、日内的负荷变化以及在线运行电站对应的出力运行情况,分析系统负荷与电站出力的不均匀性之间的相关关系,通过水电站弃水或火电站增加出力的方法将电力系统月调节系数控制在一定范围内,从而使电力系统在年、月、日内达到电力电量平衡。改进火电站群电力电量平衡计算方法,根据逐次切负荷法的计算原理,通过对单一火电站工作容量以及其调峰容量的嵌套式迭代计算,得到每座火电站年、月、日的出力过程。算例结果验证了所提方法的正确性、可行性和有效性。
[Abstract]:The calculation of power balance is of great significance to the load distribution and reserve capacity allocation of power stations designed in the power system in the future and on-line operation. At the same time, it can reduce the waste of resources for the rational use of hydropower resources and fossil energy. Environmental protection plays a guiding role in reducing emissions. In view of the annual, monthly and daily load variation of the power system and the corresponding output operation of the on-line operation power station, the correlation between the system load and the inhomogeneity of the power station output is analyzed. The monthly regulation coefficient of the power system is controlled within a certain range by the method of abandoning water or increasing the output of the thermal power station, so that the power system can reach the balance of power quantity in the year, month and day. The calculation method of power balance of thermal power station group is improved. according to the calculation principle of successive load cutting method, the annual, monthly and daily output process of each thermal power station is obtained by nesting iterative calculation of the working capacity of a single thermal power station and its peak shaving capacity. The results of an example verify the correctness, feasibility and effectiveness of the proposed method.
