Making old new again: next generation of self-reactive power compensation high surge
impedance loading (HSIL) lines engaging transmission expansion planning (TEP) can be a …

This two-part paper presents a method to mitigate half-cycle saturation of transformers
caused by monopolar operation of neighboring HVDC transmission lines while keeping the …

When HVDC transmission systems operate in the ground return mode, transformers in
adjacent ac systems frequently suffer half-cycle saturation. In this two-part paper, an effective …

Abnormal vibration may cause the internal failure of transformers. In particular, the nonlinear
saturation vibration of the iron core under direct current (DC) magnetic bias will lead to …

Recently, the grounding system of substation has been seriously invaded by earth current
generated by flourishing urban rail transit network. The invasion leads to abnormal vibration …

Direct current flow through power transformers in HVDC systems can lead to significant half-
cycle saturation issues, putting the power system at risk. The HVDC system can function in …

Direct currents can cause significant half-cycle saturation issues with the power transformers
used in HVDC systems, posing a serious threat to power systems. This research introduces …

This dissertation presents wide-area measurement-driven approaches for power system
modeling and analytics. Accurate power system dynamic models are the very basis of power …

The synchronous condenser is used to supply reactive power for HVDC converter station
through the power transformer. The DC power that invades the power transformer biases the …
