交直流融冰电源的研究及应用

Researches And Application Of AC/DC Ice-melting Power Supply

输电线路作为电能传输的重要通道,一旦发生覆冰故障会对电网的安全稳定运行造成不可估量的影响,因此只有对基于热融法的交直流融冰技术进行及时、合理的应用,才能避免或减少覆冰对线路的不利作用。在交直流融冰技术应用过程中,交直流融冰电源的供电至关重要。提出了系统电源与交直流融冰装置结合的供电方式,并分析了交、直流融冰电源的区别及适用范围,以期为现场的线路融冰提供技术支持。

Transmisson line is important access to electricity transmission, the failure of its Icing will have inevitable effect on the security and stability of Power Grid. As a result,only by adopting AC/DC Ice-melt- ing technology on time which is based on heat-melting, can the negative effect to Icing lines be avoided or reduced. In the application process of AC/DC Ice-melting, the power supply of AC/DC Ice-melting is cru- cial. System sources and AC/DC Ice-melting equipment constitutes the Power supply, at the same time, the difference and adaptation of AC/DC Ice-melting sources are analysed, which may provide the technical support for transmission lines Icing.
