However, the increasing penetration of converter interfaced sources (CIS) (e.g. wind, PV, HVDC systems, etc.) could significantly reduce the system fault level and change the fault characteristics, thus presenting challenges to the reliable operation of LCD protection. In this paper, the impact of the integration of CIS on LCD performance is investigated comprehensively. Analytical expressions representing LCD relay operation in the presence of converter-driven fault currents and weak infeed conditions have been developed. A test network, comprising of a CIS model equipped with a typical converter fault-ride through strategy that is compliant with the GB Grid Code, has been built in a Real-Time Digital Simulator (RTDS). Simulations of LCD performance for different fault and system conditions are performed and presented. It is demonstrated that the dependability of the LCD relay can be compromised during internal phase-to-phase faults. The results also show that with the synchronous generation being displaced by CIS, the increasing CIS penetration and fault contribution from the CIS can lead to an increased phase angle difference between the fault currents contributed from the two ends of the protected line, which will increase the risk of the compromised protection performance.","PeriodicalId":427816,"journal":{"name":"16th International Conference on Developments in Power System Protection (DPSP 2022)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131378278","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}

A digitally distributed busbar protection system is often implemented using the proprietary technology of the numerical relay’s original equipment manufacturer. The IEC 61850-9-2 standard for process bus communication and the IEC 61850-9-2 Light Edition (LE) guidelines provide a standardized and interoperable IEC 61850-based distributed busbar protection system and digital secondary system (DSS). This paper introduces several of the necessary test processes and performance metrics sufficient for a DSS installation and the specific commissioning results for a DSS serving a large, distributed busbar protection application. This paper discusses an IEC 61850-9-2 process bus, Precision Time Protocol (PTP) power profile, and software-defined networking (SDN)-based busbar protection system, which was implemented at a 400 kV substation for the Power Grid Company of Bangladesh (PGCB). The implemented solution protects four diameters of a one-and-a-half breaker busbar scheme and has the capacity for future expansion to accommodate up to eight diameters. This paper also discusses lessons learned from the project and provides data and evidence of the health and performance of the process bus-based DSS protection system.","PeriodicalId":427816,"journal":{"name":"16th International Conference on Developments in Power System Protection (DPSP 2022)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122482768","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}
