电力变压器的经济运行

Economical Operation of Power Transformer

变压器损耗在电力系统能量损耗中占有很大的比例,在电力系统可靠供电的前提下,合理选择变压器的运行方式,可以优化变压器的功率损耗,实现降损节能。首先分析了变压器功率损耗和运行效率的关系,然后根据不同的负载情况,计算变压器并列与分列运行的临界条件,最后讨论了实际运行中选择变压器运行方式应该考虑的因素,来实现变压器可靠、经济、高效的运行。

The power loss of transformer has a large proportion among that of power system.Under the premise of reliable powersupply,reasonable choice of transformer operation mode can optimize the power loss of the transformer to achieve loss reductionand energy conservation.In this theses,the relationship between power loss and efficiency are analyzed and paralleled and disaggregate critical conditions are figured out aiming at various circumstances.Finally,some factors that should be taken into account whenchoosing its operation mode are discussed to assure transformer to operate reliably,economically and efficiently.
