IV. Result of Research and Development
For development it has performed analysis of existing data detailed design and verification of each component of propulsion control device prototype and LCC analysis of existing propulsion control device at the first and second year.
The main component of the cube and the assembly plant for the test was conducted at the third year. The performance was confirmed through on-track test combination test for prototype at the fourth year.
Research managing department is Korea Railroad Corporation committed research institution is Korea Railroad University Moasoft and Woojin E-kyoung is joint research institution.

ㅇ SE activity
For the process control WBS has made out shared to each institution and then systematic research and development can be possible. As railroad operating institution we take action to apply user requirement and actively support the review of technology document and on-track test.

ㅇ RAMS application research
RAMS is largely H/W S/W and for the application of RAMS BOM data organized by each separately it has researched reliability forecasting model. For application of S/W RAMS software requirement specification standard draws up: software specification makes out software code standard software test plan procedure and result prepared.

ㅇ LCC analysis of propulsion control device
For LCC analysis of KTX propulsion control device it has compared LCC analysis of existing motor block and LCC analysis of development product.

ㅇ propulsion control device cube single component test
Cube is carried out in single component test by railroad specialized inspection institution. Vibration and environment test is confirmed by outside certificate authority that it is in a good condition. Also after installing to on-track train has operated from Seoul to Busan (3,770 km achievement) and it has confirmed that it is in a good condition.

ㅇ propulsion control device plant test
For combination test the same facility with KTX constructed and carried out combination test by railroad specialized inspection institution.

ㅇ propulsion control device on-track test
On-track test of propulsion control device assembly (except controller) is largely divided into static test and dynamic test； it has estimated temperature and performance between existing product and development product. As a result the only difference is that sensor specification between converter and motor sensor are different.
