Embodiment Construction

[0048] Basic setup: Take one IHC system to set up two production lines as an example.

[0049]Note: Before the IHC system is put into full-automatic operation, the operator needs to check the communication status between the PLC and the central control room of the hydropower station, check the electric valves, flow transmitters, The working status of the pressure transmitter and the safety valve, and the on-site operation of the booster chamber emptying valve and the ecological flow valve to discharge the air in the IHC system.

[0050] 1. After receiving the instruction from the central control room of the hydropower station, the IHC system starts to run;

[0051] 2. The electric valve of the water intake, the water inlet valve of each booster bin and the isolation valve of the booster bin are opened, the outlet valve of each booster bin is closed, and the ecological flow valve is closed; flush water to each booster bin;

[0052] 3. When the pressure in No. 1 pressurized cha...

Abstract

The invention relates to the field of electric energy, and discloses a system for increasing the hydraulic head and installed capacity of a hydropower station and a control method of the system. The system and the control method are applicable to newly-built large, medium and small hydropower stations and the expansion of in-service hydropower stations. One set of the system comprises a pluralityof production lines, and each production line mainly comprises a water inlet pipeline, a pressurization bin, a water outlet pipeline, an electric valve and a control device. Water flows through the water inlet pipelines to enter the pressurization bins, and is pressurized and then discharged into energy increasing bins through the water outlet pipelines in a circular and continuous manner, so thatthe hydraulic head is increased, and the power generation flow is ensured. Because the hydraulic head is increased, the installed capacity and power generation of the hydropower station can be greatly increased. The system and control method are small in investment and huge in investment return; and natural resources can be sufficiently utilized to ensure the ecological flow of rivers, and therefore remarkable environmental protection and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of electric energy, in particular to "a system for increasing water head and increasing installed capacity of a hydropower station and a control method thereof". Background technique [0002] As clean energy and low electricity prices, a large number of hydropower stations have been built around the world. [0003] As we all know, the installed capacity of hydropower stations mainly depends on the head and flow of the river. Under the premise that other conditions remain unchanged, if the water head is higher, the installed capacity of the hydropower station will be greater; the greater the flow, the greater the installed capacity of the hydropower station (the formula for calculating the installed capacity of a hydropower station: installed capacity = acceleration of gravity x flow x water head x turbine and power generation machine efficiency). [0004] According to the traditional design, after the location of th...
