GB/T 25117.3-2010 Railway applications—Rolling stock—Combined testing—Part 3:Combined testing of alternating current motors fed by an indirect converter and their control system (English Version)
Railway applications—Rolling stock—Combined testing—Part 3:Combined testing of alternating current motors fed by an indirect converter and their control system
This part applies to the combinations of motor(s), indirect convertors and their control system and its object is to specify:
— the performance characteristics of electric drives consisting of a convertor, alternating current motors, and the related control system;
— methods of verifying these performance characteristics by tests.
Two categories of combined systems can be considered:
a) Alternating current motors fed from a convertor without any control between the mechanical output (torque, speed) and the convertor itself (mostly auxiliary motors, for example cooling fan motors). The motor works exactly as if it were fed from a busbar (at variable frequency and voltage or not).
b) Alternating current motor(s) (paralleled or not) with a control between the mechanical output and the inverter.
The first category of systems is tested according to GB/T 25123.2-2010 and GB/T 25122.1-2010.
This part applies to the second category, mainly traction drives.
GB/T 25123.2-2010 applies to convertor-fed alternating current motors, GB/T 25122.1-2010 to power electronic convertors; GB/T 25119-2010 applies to electronic equipment; this standard applies to the combination of motor(s), convertors, and their control system. As a consequence, GB/T 25123.2-2010 describes the tests to demonstrate the compliance of the motor to its specification, GB/T 25122.1-2010 does the same for the convertor. It is self-evident that some of the tests mentioned in this standard may in general replace the corresponding ones described in the above mentioned standards. An agreement should be reached between the parties to avoid the duplication of tests.
A complete combined test is heavy, and often requires high power, which is not always available in workshop. An agreement between user and manufacturer may be reached to allow testing either in the workshop or on the vehicle.
At the time of drafting of this standard, only the following combinations of motors and inverters have been used for traction applications, but it may also apply to other combinations which may be used in the future:
— asynchronous motors fed by voltage stiff (voltage source) inverter;
— asynchronous motors fed by current stiff (current source) inverter;
— synchronous motors fed by current stiff (current source) inverter.
The input of these inverters (see figure 2) can be a d.c. supply line or an intermediate d.c. link, which can be obtained from an a.c. line by means of a rectifier (2.2.1 of GB/T 25122.1-2010) or from a d.c. line by means of a chopper (2.2.2 of GB/T 25122.1-2010) or from autonomous supplies (such as on-board generators, accumulators or other electric energy sources) (1.1 of GB/T 25122.1-2010).
