The role of electronic load controllers in reducing the cost of small hydro schemes is explained with particular reference to the situation in Papua New Guinea. A prototype controller based on an AIM 65 microcomputer is described. Program algorithm and input/output circuitry are covered in detail. Conditions necessary for stable load controller operation are discussed and quantified. Laboratory and field test results are given, with indications of likely future developments.
