Wind farms or wind power plants (WPP) and solar power plants (SPP) are the most actively developing types of energy sources on the RES basis. As a result, the wind power global capacity was about 487 GW by the end of 2016, solar global capacity − 303 GW. It shows an increase in wind and solar energy by 12,7% and 32,9%, respectively, compared to the previous year [1]. DG integration on the basis of wind turbines and photovoltaic panels into the electric power systems (EPS) changes the generating capacities structure, as well as causes EPS regime and emergency control problems, which in turn forces the use of completely different organization principles for control systems, in particular, for relay protection and automation (RP A). Thus, it is possible to note the main essential integration problems of DG and RES objects into EPS:","PeriodicalId":345204,"journal":{"name":"2018 International Youth Scientific and Technical Conference Relay Protection and Automation (RPA)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133825596","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}

Overcurrent protections based on higher harmonics (HH) of zero sequence current 3i0 of protected connection (OZSPHH) have received the widest application in compensated networks [3], [4]. The disadvantage of all OZSP performances is a significant effect on the efficiency of its operation of zero-sequence transient currents with arc intermittent earth faults (AISPEF), limiting selectivity and sensitivity and, therefore, possible application scope of the above protection [5], [6], etc.]. The main OZSPHH disadvantages are significant influence on the conditions of its selectivity and sensitivity of HH level instability in the current of compensated network limiting possibilities of its application, as well as protection blocking for AISPEF, to prevent unnecessary trips.

This is due to the urgency of the problem of reducing the time of FL in the case of network accidents, and the corresponding improvement in the quality indicators of power supply for consumers “SAIDI” (System Average Interruption Duration Index) and “SAIFI” (System Average Interruption Frequency Index). Among the other methods of FL, the most promising is the traveling-wave method of FL (TWFL), based on the recording of signals of the transient process arising in the network in emergency situations. The TWFL is already used in high voltage grids and shows satisfactory results. So, the devices of the American company “Schweitzer Engineering Laboratories” can, according to the company's own statements, determine the location of damage in overhead transmission lines with accuracy of one tower span [1]. For operation of such devices, the presence of measuring current and voltage transformers inside transformer substations is obligatory, because their own insulation is not sufficient for working with high voltage.","PeriodicalId":345204,"journal":{"name":"2018 International Youth Scientific and Technical Conference Relay Protection and Automation (RPA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134089997","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}
