SEVERAL HYDROPOWER PRODUCTION MANAGEMENT ALGORITHMS

In this paper the modes of operation of hydropower plants developed for use in a simulation model that is a part of a Hydro-Information System (HIS), are presented. Various methods of representation of performance of electricity generating units, turbines and generators, as well as the conduits or a plant as a whole, are described in detail. Various modes of operation of hydropower plants are presented: with specification of the daily electricity generation of the whole hydropower plant, with specification of the hydropower plant power during each hour of simulation, with the run-off-river hydropower plant operation and with explicit specification of the power, i.e. of the discharge for each unit in the plant during each hour of simulation. For each mode of operation the corresponding algorithms are described in detail. Examples of application of the modes of operation within a HIS are given. The example of operation of the “Višegrad” HPP demonstrates the hourly simulation of HPP operation with the specification of the power, while the examples of operation of the “Uvac” HPP demonstrate the simulation of the operation with the specification of daily and hourly electricity generation of the plant.
