Study on clearance optimisation and altitude correction of 750 kV AC side for UHVDC converter transformer

Study on clearance optimisation and altitude correction of 750 kV AC side for UHVDC converter transformer

AC system which ±800 kV converter station access to commonly used 500 kV voltage level. With the construction of the Northwest Energy Base, a large number of ultra-high-voltage direct current (UHVDC) project are constructing. The backbone voltage in the northwest region is 750 kV. Phase or phase-to-...
