Approximately more than 70 of these systems are 20 years and older. Earlier systems were realized with analog control systems. Some of those systems operated for over 30 years. Digital control systems were introduced in HVDC for a number of technical reasons. All systems that were installed in the last 30 years utilize digital controls. Digital controls typically have a much shorter life of 12- 15 years, with a Human Machine Interface (HMI) replacement about every 7 years. As a result, a number of systems are facing the challenge of replacing the digital control and protection systems. The control systems interact with other subsystems such as the valve base electronics (VBE), thyristor Gate Control Units, cooling controls as well as the measuring equipment. It is often challenging to decide which other related subsystems to replace (e.g. control and protection only or VBE and control and protection, or even to go further and include the cooling controls). This paper describes a process that can be followed to assist in making the decision to replace the control and protection systems, preparing the technical specification, bidding process, testing and commissioning. Even though the paper discusses Line Commutated Converters (LCC), the basic principles apply to Voltage Sourced Converters (VSC) as well}.","PeriodicalId":403034,"journal":{"name":"2021 AEIT HVDC International Conference (AEIT HVDC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125146217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the paper discusses the challenges to implement one of these converters, such as the sizing of the power electronic elements, cooling management, insulation from ground, etc. Most of them are already tackled in other existing devices in the field of high voltage.

The performances and the efficiency of these links are crucial issues as they can transmit several TWh per year, while they are supposed to remain in operation during decades.

This article deals with the use of devices with higher voltages ratings to keep the number of levels reasonable regarding the design constraints. Focusing on Integrated Gate Commutated Thyristors (IGCTs), this paper shows that 9 kV and 6.5 kV IGCTs exhibit excellent performances compared to 4.5 kV devices and that they would be ideal for future +/-640kV/1 GW symmetric monopole HVDC links.","PeriodicalId":403034,"journal":{"name":"2021 AEIT HVDC International Conference (AEIT HVDC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129610461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
