FIELD: water and heat supply systems; heat-power engineering.
SUBSTANCE: proposed system includes forward and return pipe lines, pressure bypass line with dynamic pump and shut-off and adjusting valve. Pressure bypass line is mounted on forward pipe line by means of two gates: inlet and outlet in parallel with inlet gate of main before shut-off and adjusting valve; system is also provided with generator in form of induction electric motor which is connected with dynamic (centrifugal) pump operating in turbine mode; generator is connected with consumer mains through inverter; it is provided with capacitor unit, ballast load controller for control of system through feedback couplings.
EFFECT: enhanced operational and economical efficiency.
