They both have the function to reduce the active power losses and improve nodes " voltage level 这两者都有降低网络有功损耗和提高网络节点电压的功能。
The reactive power optimization of a radial distribution system can efficiently minimize the real power losses and improve voltage level of it , so that the yearly running charge will be reduced and the quality of power energy can be increased 配电网无功优化可以有效地降低网络有功损耗,提高系统的电压合格率,从而降低网络运行费用,提高供电质量。
In at power supply system some transformers with special connection mode , such as scott transformer , anti - scott transformer , balance transformer and so on , are usual used . the voltage ratio is one of important parameters of transformer 采用斯科特变压器、平衡变压器等特殊接线方式变压器作为主变压器,能有效抑制负序电流,减少有功损耗和电压损失,提高牵引机车的过负载能力。
On the condinary , much reactive capacity loaded would be bad , and net ' s voltage would be higher and its security would be influenced . with the needs of reducing line loss , to study the method of compensating reactive capacity has been an important task in power department 同理,如果就地投入补偿过大,多余的无功就要通过输配电线路向其他设备或区域输送,也会造成无功和有功损耗,使得用户的电压偏高,影响到电力网的安全经济运行。
Capacitors dispatch of distribution system is an efficient method to network loss reduction and voltage improvement in the distribution system operation . it is an important component of distribution automation system ( das ) . the thesis mainly discusses reactive optimal control of distribution system 首先,研究了配电网无功优化控制的基本理论,讨论了配电网无功优化控制对电压和有功损耗的影响,提出配电馈线电容器优化控制对进一步降低配电网的有功损耗效果显著。
