Nowadays, the use of decentralized electricity and heat generating systems for supplying power to individual enterprises and to distant and isolated regions has become of issue. It should be noted that the demand for decentralized generation of electricity and heat can be met to a significant extent by constructing integrated power supply systems composed of nuclear power plants equipped with small- (up to 300 MW) and medium-capacity (from 300 to 700 MW) reactors, gas-turbine units (GTUs), and combined-cycle power plants (CCPPs).
An algorithm for designing the electrical part of integrated power supply systems containing small-capacity nuclear power plant units (SC NPPs), GTUs, and CCPPs has been developed. The results from elaborating different versions of shaping an integrated power supply system involving the use of combined cycle technology in an SC NPP unit and power supply systems containing electrically linked GTUs, CCPPs, and SC NPPs are presented. The integrated power supply systems comprise a modular liquid metal cooled SVBR-100 reactor with a lead--bismuth coolant (the development of which at the enterprises of the Rosatom State Atomic Energy Corporation is close to completion) with for capacity of 100 MW, power units equipped with 70 MW GTUs, and a 200 MW CCPP.
As an outcome of the above-mentioned designing activities, the parameters and types of the main electrical equipment used in the integrated power supply systems (generators and transformers) have been determined. In addition, the versions of their power output systems and the basic circuits of power unit auxiliary power supply systems have been proposed. The short-circuit fault currents have been calculated, and the types and parameters of modern switching equipment for the power units have been determined. The possibility of constructing prospective integrated power supply systems with the use combined cycle technologies and nuclear power plants equipped with small-capacity reactors has been substantiated.
