In connection with the increase in the number of high voltage and super high voltage lines in the last decade, the number of controlled cross-sections of the bulk network, those controlled by the centralized emergency control system (CECS), is increasing. Power flow calculation by the N-1 criterion in order to detect exceeding the maximum allowable power flow in the lines [2]–[4] becomes an increasingly costly computational procedure. In addition, an increase in the number of high and super high voltage lines increases the probability of stability loss outside the controlled sections. In connection with the foregoing, there is a need for a simple method that allows finding power system links that are close to the power transmission limit. Such a method would improve the efficiency of the CECS algorithms in power flow calculation by the N-1 criterion and would give the potential for control actions formulation in case of a threat of stability violation outside controlled sections.","PeriodicalId":345204,"journal":{"name":"2018 International Youth Scientific and Technical Conference Relay Protection and Automation (RPA)","volume":"37 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":"124892306","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}

However, the functions of the relay protection devices are described in accordance with the IEC 61850 information model containing logical nodes, logical and physical devices. Currently, there are a sufficiently large number of special software tools for the development of configuration description files of relay protection what are known as system configurators. Application of system configurators is intended for highly qualified specialists who, on the basis of their experience and knowledge of normative and technical documents, develop the configuration of the functions of the relay protection and automation devices. The development of the configuration of the relay protection of substation is a rather difficult and laborious task, coupled with the solution of a number of creative tasks. In this case, the probability of errors associated with the human factor is quite high.","PeriodicalId":345204,"journal":{"name":"2018 International Youth Scientific and Technical Conference Relay Protection and Automation (RPA)","volume":"98 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":"124889489","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}

The protection measures the vector sum of the currents (a differential current) on all sides of the protected object. In the case of a short circuit in the protection zone, the current rises and the protection turns off the damaged element. With an external short-circuit, the through-currents on the sides of the protected elements according to the first Kirchhoff law together give a current close to zero and called the unbalance current [2]. This current is mainly due to the error of current transformers (CTs). The error of the relaying CT depends on their load, residual induction, primary current and the presence of an aperiodic component. In the steady-state fault mode, the CT error usually cannot exceed 5% or 10%, depending on the accuracy class. However, when the primary current, secondary load or an aperiodic current is exceeded (especially in combination with the residual induction of the CT), the error may increase to 50-80%. The unbalance current increases in these modes. It can cause an incorrect operation of protection during external faults. To prevent incorrect operation of the protection the restraining is applied [3], [4]. The restraining in differential protection is an automatic increase trip current when the current through the CT is increased. Typically, as a restraint current, analog current protections use a current or several sides (legs) [5].","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":"124129757","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}
