Background technology
Railway transportation is being that China's field of traffic is seized of very important status, and many people of railway trip go away
Preferred option.Currently, trains most commonly seen, that quantity is most are air-conditioning cars（Hereinafter referred to as car）.The power supply of car
There are mainly two types of modes：One is special generator car are arranged, powered to all compartments by the generating set in generator car；Separately
One is the pantographs by car to send the electric energy on contact net the equipment such as transformer, rectifier, convertor into train,
Then it send again to each section compartment.For covering the railway operation section of contact net, car mainly uses second of power supply mode.
Maintenance gang house would generally be arranged in Along Railway, to meet the power demand of maintenance gang house, need along oriented railway orientation stand
If a special supply line, powered from special line to maintenance gang house.
The power supply mode that car and maintenance gang house are understood by investigation can be analyzed to have a power supply plan there are three to ask
Topic：First, car is higher to the reliability requirement of contact net and related power supply unit, when contact net when something goes wrong, car needs
By energy storage device（Such as accumulator）To train emergency service, the capacity of important load determines in the capacity and car of energy storage device
The length of the time of emergency service, when energy storage device configuration capacity is smaller or there are when failure, when cannot be satisfied emergency service
Between requirement, when energy storage device configuration capacity is excessive, entire emergency power supply system system investments are high, and economy is poor；Second,
Load in car is powered by contact net, and loss of the electric energy on contact net is inevitable；Third, maintenance gang house is for dimension
Shield, maintenance workpeople's lodge of railway, rest house, therefore load and little itself to meet power reguirements, but needs
Special supply line completely is set up along railway, economy is poor.Therefore three above can be solved the problems, such as simultaneously by providing one kind
New power supply mode and power supply plan there is practical significance.
Invention content
It using photovoltaic generation and energy storage device is train and railway maintenance squad that the technical problem to be solved in the present invention, which is to provide a kind of,
The facility of room power supply；The facility can either can also power to power supply for coaches to maintenance gang house, improve power supply for coaches reliability, effectively
Power grid construction investment is reduced, realizes rationally power supply.
It is as follows that the present invention solves the technical solution that above-mentioned technical problem is taken：It is a kind of to be using photovoltaic generation and energy storage device
Train and the facility of maintenance gang house power supply, include the car of headstock and more piece compartment composition；It is characterized in that：Further include being set to often

Direct current is converted into the load and the energy-storage system that are delivered to after alternating current in car by inverter.First transmission line circuit is to visitor
Interior load power supply, the second transmission line circuit are powered to energy-storage system.
The energy-storage battery of energy-storage system stores electric energy, realizes the charging of energy-storage battery by bidirectional converter, puts
Electric process；Energy-storage battery in energy-storage system is replaceable battery, it is carried from car and provides power supply for maintenance gang house.
A set of measure and control device is respectively set in every inverter and every bidirectional converter, and measurement and control signal is uploaded to positioned at vehicle
The background monitoring device of head, car driver and conductor can pass through the fortune of background monitoring assembly monitor photovoltaic generating system and energy-storage system
Row state, and by controlling inverter and bidirectional converter, control the direction of tide of electric energy.
The present invention, which realizes, can also power to maintenance gang house to power supply for coaches, improve power supply for coaches reliability, have
Effect reduces the investment of power grid construction, realizes rationally power supply.The present invention be operation principle approximately as：
（1）Under car normal operating condition
In car normal operation, direct current energy is transported to inverter, direct current is changed by inverter by photovoltaic module power generation
380 volts of electricity are exchanged, two transmission line circuits are arranged in inverter.First transmission line circuit is connected to the distribution box in car, directly to car
The loads such as interior illumination, air-conditioning and water heater are powered, and the electric energy that contact net is conveyed to car is reduced, and reduce the electricity on contact net
It can loss；Second transmission line circuit charges to the energy-storage system of objective Bus inner layout.
In car normal operation, current transformer is worked using charge mode, and energy-storage system is constantly in charged state.
In the process of running, train operation personnel can not only monitor photovoltaic system and storage to car by background monitoring device
The operating status of energy system, and inverter and bidirectional converter operating status can be controlled, determine the electric energy that photovoltaic system is sent out
Load or energy-storage system in preferential supply car.
When car stops station, the time changed to using passenger is replaced the energy-storage battery that electric energy is had been filled in car
To need the energy-storage battery to charge, continue to charge.The energy-storage battery for having been filled with electric energy is then transported to each maintenance gang house, and replacement makes
Used energy-storage battery is continuing with for service personnel such as maintenance gang houses.By recycling for energy-storage battery, maintenance gang house is realized
Continued power.
（2）Under car malfunction
In car failure, direct current energy is transported to inverter, direct current is changed into exchange by inverter by photovoltaic module power generation
380 volts of electricity, inverter are powered by important load of first transmission line circuit directly into car；Second transmission line circuit suspends work
Make.
In car failure, bidirectional converter is worked using discharge mode, and energy-storage system becomes discharge condition, to car
Important load is powered.
