With radial topology and one-way power flow, it was only necessary to evaluate the envelope of design conditions (i.e., peak loads or fault currents), rather than continually observe the operating state. But the growth of distributed energy resources, such as renewable generation, electric vehicles, and demand response programs, introduces more short-term and unpredicted fluctuations and disturbances [1] . This suggests a need for more refined measurement, given both the challenge of managing increased variability and uncertainty and the presence of a higher level of narrowband and broadband interference and measurement noise.","PeriodicalId":299510,"journal":{"name":"2020 3rd International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129596424","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}

Therefore, the disturbance of the generator and electrical station parallel work stability is the reason for decrease in auxiliary mechanism productivity at electrical stations.

At the present time in electric power industry a concept of intelligent electrical power system is realized. A key component of this system is a digital substation. One of the main tasks of digital substation equipment is realization of effective relay protection and network automation devices. Relatively new phenomenon in this field is relay protection devices, which are based on travelling wave parameters measurement. A very important characteristic of relay protection devices (especially for extra-high voltage transmission lines of 330-750 kV) is their speed-of-response. The usage of travelling wave-based principle will allow to limit speed-of-response only by travelling wave propagation time along a protected transmission line.","PeriodicalId":299510,"journal":{"name":"2020 3rd International Youth Scientific and Technical Conference on Relay Protection and Automation (RPA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129422579","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}
