【摘要】 在电力系统能量损耗中，变压器的损耗占有很大的比例，因此，全面开展变压器经济运行是实现电力系统经济运行的重要环节。本文以系统负荷预测结果为前提，针对变压器经济运行优化调度问题展开研究。在求解变压器损耗问题中，引入了潮流计算，提出了变压器各种运行方式下损耗计算的通用方案；构造出了变压器经济运行优化调度方案问题的数学模型，提出应用动态规划方法求解该问题，并给出了求解具体过程。对由两台三绕组变压器组成的系统进行计算，结果令人满意，验证了基于动态规划法求解该问题是可行的和有效的。更多还原

【Abstract】 The energy loss of transformers is great in proportion to all of energy loss in power system, and thereby implementing transformer’s economic operation play an important role in achieving economic operation of power system. In the premise of load forecast results of power system, the paper carries out research on optimizing dispatch for transformer’s operation. During the course of loss calculation of transformers, the paper imports power-flow calculation and puts forward a general loss calculation scheme under vary operation manner, and creates a mathematics model of optimizing dispatch scheme for transformer’s economic operation, and brings forward applying dynamic programming in solution to the problem, and finally presents detail calculation courses。The calculation result of power system composed of two three-coil transforms is satisfying, which proves it available to solve the problems on base of dynamic programming method.更多还原
