特、超直流输电单极大地运行时可能造成的直流偏磁现象会引起主变振动加剧、局部过热及互感器特性变化等后果,严重影响设备安全稳定运行的同时,大大增加能耗及噪声排放。项目通过机理研究、试验验证与产品研制等技术手段,形成完善的直流偏磁抑制技术体系与解决方案,可系统地解决直流偏磁抑制问题。已获发明专利受理3项。
The DC bias phenomenon that may be caused when the UHV and UHVDC units run extremely greatly can cause the vibration of the main transformer to be exacerbated, the local overheating and the characteristics of the transformer, which will seriously affect the safety and stability of the equipment and greatly increase the energy consumption and noise emission . The project will form a complete system and solution of DC bias magnetic suppression technology through mechanism research, experimental verification and product development, which can systematically solve the DC bias suppression problem. Has received three invention patents.
