Abstract

The utility model belongs to the technical field of energy source and electromechanics, and particularly relates to an induced-draft generating system of a high-speed railway. The induced-draft generating system comprises a plurality of wind turbines and small direct drive wind power generators, which are symmetrically mounted on the two sides of the high-speed railway, wherein each wind power generator is connected with a variable-speed constant-amplitude rectifying device; the variable-speed constant-amplitude rectifying devices are joined up in parallel onto a DC bus; and the DC bus is sequentially connected with a storage battery, an inverter and electrical equipment. The induced-draft generating system can effectively convert the train wind produced by the passing high-speed train into electrical energy, so as to provide energy to the nearby battery-consuming sites; at the same time, the wind turbines arranged in rows beautify the landscape along the railway, reduce the harm of the train along the railway, and achieve the purpose of achieving the usefulness from the waste.

Description

High ferro train air inducing power generation system

Technical field

The utility model belongs to the energy and mechanical ﹠ electrical technology field, is specifically related to a kind of high ferro train air inducing power generation system.

Background technique

Along with the fast development of China's communications, bullet train progressively runs through between each big city, and high ferro is because of advantage more and more is subjected to people's such as its speed is fast, steady favor.When the train high speed operation, will drive train ambient air movement therewith, form a kind of specific air-flow, be commonly called as " train wind ".Such as, average per second travelling speed is near 100 meters in the time of 350 kilometers for Zheng Xi high ferro operation speed per hour, and " train wind " air-flow of formation is extremely strong, and the pedestrian in the online roadside of very likely will walking is involved at the bottom of the train; The military wide high ferro wind speed that travels reaches 13 grades, and train far removes to take up " tornado ".Therefore, generally built protective grating according to standard and carried out closed management, do not established the level crossing with the public vehicles crisscross traffic, its objective is in order to take precautions against " train wind " in bullet train circuit whole process along the line.And military wide high ferro realized " high density " " public transportization ", and daily visiting ability reaches 8.38 ten thousand person-times, and the bob car time of originating point foreshortens to 10 minutes, makes passenger's " with to walking ".So the powerful and highdensity train wind of energy can fully be used, and changes harmful to treasure.

Summary of the invention

The purpose of this utility model is to provide a kind of power generation system of utilizing high ferro train wind, belongs to the energy development of a kind of environmental protection, cleaning.

The utility model is realized by the following technical solutions: this high ferro train air inducing power generation system, it is included in the some wind turbines and the miniature direct-drive formula wind-driven generator of high-speed railway symmetry installation along both side, each wind-driven generator is connected with the permanent width of cloth rectifying device of speed change respectively, the permanent width of cloth rectifying device of each speed change is also received on the dc bus, and dc bus is connected with storage battery, inverter and consumer again in turn.

More particularly, described direct-drive aerogenerator is installed on the fan supporter, and the front end of fan supporter is equipped with wind turbine, and tail end is equipped with the local derviation system.

And, on described wind turbine, being connected with a centrifugal switch, centrifugal switch is connected with wind-driven generator.

The utility model has adopted the many groups of wind-driven generators that are installed in high ferro train circuit along the line to carry out the team control generating, can effectively utilize the high-speed railway train by the time train wind that produces, by being converted into the electric energy form, for nearby electricity consumption place provides the energy; Simultaneously, wind turbine adopts spread pattern in a row, increased the sight of scene on the way, has reduced train wind again on the way harmfulness, has reached the purpose that changes harmful to treasure.

Description of drawings

Fig. 1 is the utility model embodiment's a theory structure block diagram.

Embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

Referring to Fig. 1, in the present embodiment, at high-speed railway three groups of wind turbines 1 and miniature direct-drive formula wind-driven generator 2 are installed symmetrically along both side, wind turbine 1 and miniature direct-drive formula wind-driven generator 2 can obtain according to experiment in the mounting point on railway limit, accomplish both can make full use of the wind energy that bullet train brings, reduce the influence of wind-power generating system again as far as possible train operation.Each wind-driven generator 2 is connected with the permanent width of cloth rectifying device of speed change respectively, the direct current that the AC rectification of utilizing the permanent width of cloth technology of speed change that wind-driven generator 2 is sent by rectifier becomes amplitude to determine; The permanent width of cloth rectifying device of each speed change again and receive on the dc bus 6.Dc bus 6 is connected with storage battery, utilizes storage battery that the electric energy that the separate unit wind-driven generator of intermittent duty obtains is put together, and by the inverter that is connected with storage battery, forms utilizable electric energy form, is transported on the consumer.

As seen from Figure 1, direct-drive aerogenerator 2 is installed on the crossover location place of the crossbeam and the straight beam of fan supporter 4, and the crossbeam front end of fan supporter 4 is equipped with wind turbine 1, and tail end is equipped with local derviation system 3.Local derviation system 3 on the wind turbine 1, can be automatically with the wind turbine blade front towards train wind, when making train 5 come and go operation, power generation system all can normal power generation.

And, on wind turbine 1, being connected with a centrifugal switch, centrifugal switch is connected with wind-driven generator 2.

The centrifugal switch that utilizes wind turbine to drive can guarantee when exceeding design wind speed, cuts off generator circuit, guarantees the safe operation of power generation system.
