Abstract

Purpose. In the paper there is the comparative analysis of standards and methods of measurements of electromagnetic interference, those are caused by electrical equipment of new types of rolling stock with AC and DC-current electric traction in accordance with the normative documents are adopted in Ukraine and the EU. The development on this basis the measuring method of current interference in traction network, generated by the electrical equipment of electric rolling stock (ERS) applicable to testing the new types of rolling stock for electromagnetic compatibility (EMC) with different systems of railway signaling is also needed. Methodology. The testing method has been offered. It includes measurements in power circuits of rolling stock, as well as in track devices of signalization systems. Findings. Norms and methods tests of a rolling stock on electromagnetic compatibility with track circuits (TC) were analyzed. It was found that a large variety of electricity supply systems, signalization and link in Europe makes it necessary to test new types of electric rolling stock for electromagnetic compatibility with pick up unit in each country separately, taking into account the features used in its systems. It is greatly increases the cost of introducing new types of rolling stock. The test method of electric rolling stock EMC with track circuits has been developed; it includes measurement in power circuits of rolling stock, as well as in track devices of signalization systems. Measurements in accordance with the proposed methodology for electric rolling stock with asynchronous traction drive when driving on sections electrified at AC and DC have been carried out. The values of the interference current in track circuit to all the frequencies of the signal current have been defined. It is shown that under some modes of the train the interference current exceed the permissible values. Originality. The method for measuring interference current generated by rolling stock electrical equipment in the traction network was offered. The method assumes the simultaneous recording of the network current of electric train, automatic locomotive signaling current, train`s speed, driver`s controller handle position and reverse traction current in a track line when trains passing over the measuring section with subsequent computer processing results, computer and physical simulations. Practical value. Using of the developed method improves the accuracy of the tests and reduces their cost.
