Protection for HVDC Transmission Lines Based on Current Ratio of DC Filter and Smoothing Reactor

Protection for HVDC Transmission Lines Based on Current Ratio of DC Filter and Smoothing Reactor

A new line protection for HVDC systems using the ratio of currents of a DC filter and smoothing reactor is presented. Characteristic analysis on a DC filter shows that it behaves like an inductor at a high frequency band whose inductance is far less than the sum of smoothing reactor inductance plus...
