Enhancements to a Network Analyzer for Real-Time Power System Control Studies

This paper describes modifications and additions made to a static analog network analyzer to make it behave as a realistic and dynamic power system model. The modified analyzer, combined with a full-scale control system, forms a unique tool for power system control and operation studies. All power system dynamics which are relevant from a control system point of view must be modelled. This implies that new power plant models and dynamic load models have been added to the analyzer. A metering system, used to measure interesting signals in the model, has also been added and serves as well as an interface to the control system The modified analyzer presented here is now a realistic model of the power system and, used with the control system, provides an excellent point of departure for further research.
