PROCESS OF UNINTERRUPTED ELECTRIC POWER SUPPLY OF USERS OF ELECTRIC POWER SYSTEM OPERATING ON RECOMMENCED SOURCES OF ENERGY Russian patent published in 2000 - IPC

FIELD: power engineering, organization of electric power supply of DC and AC essential services with high-power loads. SUBSTANCE: objective of invention consists in increased reliability of power supply of services thanks to prolonged duration of mode of consumption of peak loads by service caused by usage of accumulators of required capacity and by reduction of losses for additional adjustment of parameters of AC source and in expansion of functional capabilities of process thanks to widening of range of power of power system substantially exceeding power of recommenced energy sources and to raised number of services connected to power system. Process includes conversion of energy of primary recommenced source with the use of electric generator to AC electric energy, conversion of AC electric energy to DC electric energy with the aid of rectifier, storage of this energy in accumulator charged from rectifier, conversion of DC electric energy to AC electric energy by means of inverter and its supply to services. In this case electric power system employs at least one more independent source of recommenced power operating simultaneously with first one and storage of electric energy is carried out by accumulation of summary DC electric energy produced as result of conversion of energy of each primary source of recommenced power operating at same time. Volume of energy stored in accumulator is determined by its capacitance C_a that is computed by value of day power consumption by service. Operational mode of generator is controlled by change of capacitance of resistance of accumulator in process of its charging with keeping of value V_ch of charging voltage preset in range between minimal and maximal voltage values across load of service. Electric power system can employ two sources of recommenced energy operating at same time, for example, wind-wind or two sources of recommenced energy of different types operating at same time, for example, wind-water. EFFECT: increased reliability of power supply of essential services. 2 cl, 3 dwg
