The problem of energy efficiency in the public transport and its solution

The problem of energy efficiency in the public transport is in sharp changes in energy networks and small use of recovered energy. Trams and trolleybuses can recover energy, but almost all of it is "burned" to the brake resistor is not used again.

Effective use of recovered energy is possible when using a flywheel storage. With fast energy storage is carried out fast and its recoil. Energy Storage also helps to smooth the voltage fluctuations in the network.

Construction and operation of the IRC

Recovered energy is supplied to the motor-generator, which spins up "a high-energy flywheel" energy intensity to 8 MJ (about 2 kWh) of energy. If necessary, the motor-generator converts the kinetic energy stored in the electric current, and then outputs a contact network. Energy storage is equipped with a control unit. As to the coupling of the stationary contact and IRC network, communication can be performed with the contact portion of the network directly or via a substation.

Application of FEM for recovery trolley / streetcar energy

The recovered energy is currently little used on the network repeatedly. With IRC it promotes acceleration of the car. Due to the accumulated energy can accelerate the car up to 40-45 km / h. At one stop requires one SCE, taking into account the simultaneous inhibition 3-4 trams or trolley buses.
To calculate the recovery efficiency must be drawing up the load curve on the network (on traction substation or between substations). Frequency of transport recovery cycles directly affect the effectiveness of the buffer storage and energy return. Total savings (only for electricity) per year, with one stop will be 16,685 dollars (not including braking at traffic lights). If the IRC set 50 stops, the savings for the year amount to 834,286 dollars.

Benefits of Using IRC

Tests in steady NCE storing, issuing energy recovery mode, EPS showed excellent results. In the dispersal of one trolley / streetcar energy savings of approximately 0.5 kWh. By the way, one day after a lively platform takes about 600 cars. The modern city has over 800 trams. Besides the cars slow down in traffic jams and at traffic lights. Stationary SCE is able to work with the trolley, tram, train and subway. SCE is able to work more than 20 years. The use of stationary storage also reduces the thermal load on the environment, a smoother movement of cars and a significant reduction in the cost of urban transport content.
