巴慕达音箱维修柔性直流和常规直流输电

　　recent years，my country's DC technology has developed faster，Transmission from long distance、DC transmission technology is used in multiple fields to new energy access.。DC transmission and communication transmission have advantages，DC transmission is mainly used in transmission or grid isolation，Flexible DC and conventional DC difference，Flexible DC uses full control device for controlling，Conventional direct flow is a semi-control device for controlling，The biggest advantage of flexible DC is that there is no demand for reactiveness.，And the harmonics are particularly small，Conventional direct flow requires a lot of reactive 巴慕达加湿器维修 support and a large number of filter equipment，From reliability，Conventional DC reliability is relatively high。

　　Flexible DC as a new technology，It is characterized by higher technical requirements.，Special high in real time。When the trend changes，Flexible DC can be2Millisecond completion0Change to maximum loss of power，Conventional DC control cycle is20millisecond。

　　Conventional DC voltage level。Long distance transmission±500Kilovollar、±800Qianlu is used in conventional direct flow。Secondly, routine DC conveying capacity is relatively large.。Before3000Mega，Now that it has reached4000MW even6000MW。The flexible DC technology development 巴慕达音箱故障代码 voltage level is relatively low，internationally±320The kV flexible DC project has begun construction，Positive and negative500Tricolar is gradually broken through，Technical conditions are gradually BALMUDA烤箱维修 maturing。
