FIELD: electrical engineering.
SUBSTANCE: invention relates to the electrical equipment. Combined system for starting and smoothing graphs of loads of autonomous gas-piston and diesel-generator sets using high-power storage batteries, including operations of conversion of internal energy of fuel into electric energy of standard frequency and voltage, accumulation of electric energy into batteries of capacitors in mode of normal power consumption, supply of electric energy from capacitors bank and accumulator battery to input of frequency converter and voltage, interconnected operations of reactive power calculation in unit of reactive current sensors, output of reactive power sensor operation results to frequency converter input and power plant forcing by reactive power, where instead of conventional start-up batteries two groups of high-capacity accumulator batteries are installed, connected to each other by the first double-pole breaker, consisting of blocks of series-connected and parallel connected accumulators, which in normal mode are connected to each other in series and operate through frequency converter and voltage and connected in series matching transformer to network for smoothing of load graphs, first group of batteries is connected to primary motor through second double-pole breaker and is used for start-up of autonomous gas-piston and diesel-generator plant, in mode of maximum output of power to the network and simultaneous start-up of the engine, groups of batteries can operate independently with the open-circuit first double-pole breaker and the closed single-pole breaker.
EFFECT: technical result consists in improvement of efficiency of start-up of primary electric motors and smoothing of load curves during operation of self-contained gas piston and diesel-generator sets using accumulator batteries of high power.
