The cost of the current generation of personal computers is such that it is now economical to simulate distribution systems particularly in industry to optimise their performance. Personal computers offer a price performance ratio better than minicomputers or mainframes, and can provide adequate processing power and graphics at a reasonable price for most studies. This paper describes a package of power systems simulation programs, their application to real problems in industry and their use in continuing education workshops for practising engineers. The paper concludes that every engineer should have his own personal computer and that more training is required for engineers from industry in the field of computer applications. Personal computers, together with appropriate software, are especially useful for engineers working in operations as well as in design.
