Description

A kind of tramcar mixed power supply system
Technical field
The invention belongs to field of track traffic, more particularly to a kind of tramcar mixed power supply system.
Background technology
There are two types of existing energy storage type tramcar electric power systems, the first is as energy storage member using only super capacitor The electric power system of part is for second the electric power system using only accumulator as energy-storage travelling wave tube.
As shown in Figure 1, using only super capacitor as energy-storage travelling wave tube tramcar electric power system include it is at least a set of Super capacitor 4, wherein super capacitor 4 are electrically connected with high voltage dc bus 1, the electrical equipment 2 on tramcar(Trailer system 201st, auxiliary system 202, DC frequency converting air-conditioner 203)It is electrically connected with high voltage dc bus 1, high voltage dc bus 1 can also be in electric car It is electrically connected when stopping with ground charger 3.Super capacitor 4 in parallel is female to the DC500V-DC900V high voltage direct current of tramcar Line 1 is powered, and all electrical equipments 2 of tramcar obtain the high voltage direct current of DC500V-DC900V from high voltage dc bus 1. Fig. 2 is the tramcar electric power system physical circuit figure powered using only super capacitor.
Since super capacitor charges soon, thus individually the electric power system of super capacitor power supply disclosure satisfy that the charging time of stopping Requirement no more than 30s.But since monomer super capacitor energy-storage is few, while roof installation space is limited, to super capacitor Limited Number system, the super capacitor utilisable energy for causing permutation vehicle are about 9 ~ 14KWh, and super capacitor course continuation mileage is short, and vehicle exists The course continuation mileage in straight road is about 2 ~ 3km, is waiting traffic lights, is climbing the complex road conditions such as long ramp, vehicle course continuation mileage will significantly It reduces, functional reliability is low.
Since the tramcar course continuation mileage of pure super capacitor power supply is short, in order to ensure the normal operation of vehicle, substantially often Station is required for setting ground charger 3, it is ensured that after vehicle stops, can be charged by ground charger 3 for vehicle super capacitor.
As shown in figure 3, include at least one set of store as the tramcar electric power system of energy-storage travelling wave tube using only accumulator Battery 6, wherein accumulator 6 are electrically connected by bidirectional charger 5 with high voltage dc bus 1, the electrical equipment 2 on tramcar (Trailer system 201, auxiliary system 202, DC frequency converting air-conditioner 203)It is electrically connected with high voltage dc bus 1, high voltage dc bus 1 It can be also electrically connected when electric car stops with ground charger 3.Accumulator 6 in parallel gives the DC500V-DC900V high of tramcar Pressure dc bus 1 is powered, and all electrical equipments 2 of tramcar obtain the high pressure of DC500V-DC900V from high voltage dc bus 1 Direct current.
Since batteries to store energy ability is strong, thus course continuation mileage is longer.But since the power density of accumulator is low, because And the startup power that more set accumulators just can guarantee vehicle is needed to configure, it is limited by installation space.Simultaneously as large current density Electricity can influence the service life of accumulator, be the service life for not influencing accumulator, and the generally requirement of accumulator single charge time is not low In 6 ~ 10min, requirement of the charging time no more than 30s of stopping can not be met, influence the conevying efficiency of electric car.Further, since it stores Battery cycle charge-discharge number is less, and the life-cycle service life that can influence tramcar is used as main energy sources.
