Problems solved by technology

However, the method for improving the energy efficiency of the peak-shaving power supply is not disclosed in the reference document. In addition, because the storage container is placed on the seabed, the construction and maintenance costs are high, and it is not suitable for large-scale promotion.

Embodiment 1

[0044] As shown in Figure 2(a), it is a control method for the user side from the peak period of power consumption in the daytime and the first half of the night to the valley period of power consumption in the second half of the night and early morning. Due to the large amount of power supply during the peak period of power consumption, the power surplus gradually increases in the process of gradually reducing the demand on the user side; after receiving the instruction of reducing user demand, the control center comprehensively Adjust the opening of each control valve and the distribution ratio of power supply, the air flow valve 5 and the fuel flow valve 6 are reduced; the ratio of gas turbine 3 and steam cycle unit 4 to the user side power supply is reduced; gas turbine 3 and / or steam cycle unit 4. Increase the power supply ratio of the electric motor unit 8; adjust the opening degree of the water volume regulating valve 11 according to the demand of the reversible water tu...

Embodiment 2

[0046] As shown in Figure 2(b), it is a control method for the system when the demand on the user side gradually transitions from the valley period of electricity consumption in the second half of the night and early morning to the peak period of electricity consumption in the daytime and the first half of the night. Due to the relatively small power supply during the valley period of power consumption, the power shortage gradually increases in the process of gradually increasing the demand on the user side; upon receiving the instruction of increasing user demand, under the premise that the various indicators of the system unit can be deployed within the limits, The opening of each control valve and the distribution ratio of power supply are comprehensively allocated, and the opening of air flow valve 5 and fuel flow valve 6 is increased; the ratio of power supply to the user side of gas turbine 3 and steam cycle unit 4 is increased or completely supplied to the user side; The...

Embodiment 3

[0048] As shown in Figure 2(c), in the sudden cold weather and other rapid and extreme cooling weather, the heat supply demand on the user side increases rapidly; due to the increase in heat supply demand, under the premise that the various indicators of the system unit can be allocated, the comprehensive By adjusting the opening of each control valve and the distribution ratio of power supply, the opening of the air flow valve 5 and the fuel flow valve 6 increases; in the steam cycle unit 4, within the steam extraction limit of the steam turbine, the heat supply to the user side by the steam extraction of the steam turbine increases, that is, to The heat supply ratio on the user side is increased, and the power supply ratio is decreased; the power supply ratio of the gas turbine 3 to the user side is adjusted in real time; the working conditions of the motor unit 8 and the generator unit 10 are adjusted in real time; the opening of the water volume control valve 11 is adjusted ...

Abstract

The invention discloses a method and a system for improving the energy efficiency of a peak regulation power supply by vertical pipe charging and discharging seawater storage. The system involves a vertical pipe set, a motor unit, a reversible type water pump water turbine set and a generator unit, wherein the upper end of the vertical pipe set is closed and extends out of the sea level in the vertical direction, the lower end of the vertical pipe set extends into the sea and is connected with the reversible water pump water turbine set, the reversible type water pump water turbine set is provided with a water inlet stop valve and a drainage stop valve in parallel, the reversible type water pump water turbine set is connected with the generator unit and is arranged on the seabed, and the two ends of the motor unit are respectively connected to the reversible type water pump water turbine set and a gas-steam combined cycle unit; in the electric valley period, excess output power in thegas-steam combined cycle unit drives the motor unit to rotate, water in the vertical pipe set is discharged by the reversible type water pump water turbine set, energy is stored in the vertical pipe set, and energy waste is reduced; and one end of the vertical pipe set is exposed out of the sea surface, a vent hole communicates with the inner part of the vertical pipes of the vertical pipe set, and the pipe wall of the vertical pipe set is small in pressure, low in material requirement and low in construction cost.

Description

technical field [0001] The present invention relates to the technical field of electric power energy storage regulation, further relates to the technical field of gas-steam combined cycle peak regulation, and in particular to a method and system for improving the energy efficiency of a peak regulation power supply by charging and discharging seawater energy storage through vertical pipes. Background technique [0002] Electricity occurs simultaneously from production to transmission to use, and it is generally impossible to directly store electricity on a large scale; in practical engineering applications, the demand-side load fluctuates greatly due to the influence of day, night, and season, and is often related to the output of the combined heat and power system. The electric power does not match; the demand for electric load changes rapidly. For example, in a day, the power demand during the low peak period in the second half of the night is often half or even less than th...
