Probabilistic Evaluation of Human Safety near HVDC Ground Electrode

A computer oriented method to calculate the total accident probability of the HVDC grounding system is developed in this paper in order to evaluate the safety level of it. The method is derived step by step, from the basic statistical parameters, based on the peculiarity of the dc grounding electrode. A detailed computational procedure is illustrated by block diagram. The application of the proposed method is explicated in this paper with a simple numerical example.
