Abstract

This paper deals about valve losses review of HVDC converter stations in Korea. Technique of calculating losses is one of important verification process to evaluate systems performance, so customers have right to get accurate imformation of losses in precedure of bid. It is very important to verify documents which are submitted by maker, however it is not easy for utility company to verify maker’s documents because of getting limited imformation from makers. Losses of a converter station can be easily estimated from calculation of two main equipments, valve and transformer, because proportion of two equipments accounts for more than 80% of the total values in the HVDC converter station. In this paper, authors firstly analyzed calculating process of valve losses and verified if the calculated results are accorded with the reports provided from maker in accordance with the IEC standards, IEEE standard, EPRI Handbook in case of Jeju No.2 converter station in Korea. After that, it was verified whether the results were satisfactory compared to KEPCO’s specification.
