Abstract

A substation direct current power supply apparatus taking a lithium ion battery as an energy storage device is disclosed. The substation direct current power supply apparatus is used for the substation direct current power supply apparatuses of railways, urban mass transits, power transmission and transformation, streetcars, trolley buses, mine enterprises and the like. According to the substation direct current power supply apparatus taking the lithium ion battery as the energy storage device, the energy storage battery takes the lithium ion battery to replace a cadmium-nickel storage battery or a lead-acid storage battery; meanwhile, a lithium ion battery management system is adopted for a matching use ; the technological modes including an electrical wiring mode, switch combinations and parameters, and the like are consistent with the scheme of the conventional substation direct current power supply apparatus . The substation direct current power supply apparatus taking the lithium ion battery as the energy storage device has the advantages of light weight, small size, long service lifetime, high charging/discharging efficiency, no pollution and the like; and in addition, the operation reliability and safety of the substation can be improved, and the operating cost is reduced.

Description

Lithium ion battery is as electric substation's continuous-current plant of energy storage device
(1) technical field
This technological invention is used for the continuous-current plant of institute of the electric substation electricity consumption of the technical fields such as railway, urban track traffic, a power transmission and transformation, tramcar, trolley bus and bargh.
(2) background technology
Current rail, urban track traffic, send out in the electric substation of transmission of electricity, tramcar, trolley bus and bargh, be provided with the continuous-current plant of institute's electricity consumption, arrange the storage battery of storage of electrical energy in continuous-current plant, storage battery generally selects nickel cadmium cell or lead acid accumulator.Nickel cadmium cell and lead acid accumulator floor space are comparatively large, and operation maintenance is complicated, also have that cycle life is short, continuous discharge ability is weak and need the shortcomings such as periodic maintenance, and operating cost is higher, and electric substation's operational efficiency is lower.
Electric substation is unmanned, the modern management level of few people on duty improves day by day, the continuous-current plant of institute of electric substation electricity consumption is proposed to the requirements such as reliability is high, maintenance less, the life-span is long, pollution-free, floor space is few, the corresponding raising of performance need of the storage battery of configuration.Lithium ion battery is later than the storage battery that lead acid accumulator grows up, have lightweight, volume is little, the life-span is long, voltage is high, efficiency for charge-discharge is high and the advantage such as pollution-free, be used widely in consumer electronics, but not application in the continuous-current plant of institute of electric substation electricity consumption.
Using lithium ion battery as the continuous-current plant of institute of the electric substation of energy storage battery electricity consumption, electric substation's reliability of operation and fail safe can be improved, and reduce operating cost.
(3) summary of the invention
The technical problem that the present invention solves is: existing electric substation continuous-current plant adopts nickel cadmium cell or lead-acid battery as energy-storage battery, there is the problem that cycle life is short, continuous discharge ability is weak and need periodic maintenance in battery, causes that the life-span of continuous-current plant is short, continuous discharge ability is weak, needs periodic maintenance and the larger problem of floor space.
The technical scheme of technical solution problem of the present invention is: adopt have extended cycle life, the strong and simple storage battery of maintenance work of continuous discharge ability, replace the existing nickel cadmium cell generally applied or lead-acid battery.
The embodiment of technical solution problem of the present invention is: adopt lithium ion battery to substitute nickel cadmium cell or the lead acid accumulator of existing electric substation continuous-current plant, supporting lithium ion battery management system simultaneously, other technologies mode, comprise electrical wiring form, switch combination and parameter etc., continue to use the scheme of existing electric substation continuous-current plant.
(4) accompanying drawing explanation
Accompanying drawing is that lithium ion battery electric substation continuous-current plant forms schematic diagram.In figure, device mainly comprises: 1 group of lithium-ions battery, 2 groups of chargers, load-side control loop, load-side closing circuit, voltage monitoring loop, insulating monitoring loop and battery management systems.2 groups of chargers are for subsequent use each other, to battery charging, batteries provides direct current energy by the closing circuit of load-side to load, load-side control loop is used for the closing circuit of control load side, the voltage of voltage monitoring loop monitoring batteries, insulating monitoring loop monitoring DC electrical loop whether there is Leakage Current, battery management system is responsible for the management of charging and discharging of storage battery.
(5) embodiment
Lithium ion battery is as electric substation's continuous-current plant of energy storage device, and storage battery selects lithium ion battery to substitute nickel cadmium cell or lead acid accumulator, simultaneously supporting lithium ion battery management system.Other technologies mode, comprises electrical wiring form, switch combination and parameter etc., continues to use the scheme of existing electric substation continuous-current plant.
