ABSTRACT

This paper concerns the industry-owned part of the electric power supply to an industrial load, in short: the industrial electricity supply. In the reliability assessment of the industrial electricity supply we can distinguish four main areas: finding a suitable description for the behaviour of network components; calculating the (stochastic) system behaviour from the known component behaviour; describing the (deterministic) system behaviour during a disturbance; and linking the behaviour of the protection to the system reliability.

After a discussion on the reliability problem of the electricity supply the four main problem areas are discussed in detail.
