The (N-1) criterion is considered for the design of these systems. Partial or total blackouts are unavoidable in them. There is a mechanism denoted as cascading failures which is considered as the main cause for blackouts in power systems. The propagation of cascading failures in power systems results from local activation of protective relays due to overload or voltage drop. Special protection schemes (SPS) are designed to alleviate voltage drop and line overloading by fast load shedding. Because the SPS work fast following the initial disturbance, they can quickly control the line loading and voltage drop and consequently can reduce the potential for propagation of cascading failure. In this paper, the impact of SPS on the propagation of cascading failure and their associated load loss in Iran power grid is investigated. In order to simulate the mechanism of cascading failure and the impact of SPS on that, by using Power Factory® software and modelling all control and protection devices within that, cascading failure simulating module (CFSM) is developed which is able to simulate of cascading failure mechanism. In Iran power system, 5 types of SPS have been used. By simulating 30 multiple contingencies, it is shown that in the case of severe contingencies SPS can alleviate the consequence of cascading failure.","PeriodicalId":314748,"journal":{"name":"2023 International Conference on Protection and Automation of Power Systems (IPAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126492063","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}

If these relays malfunction, some specifications of the power system may be out of standard range such as increase or decrease of voltage, frequency and other electrical specifications. To prevent such problems, the relays must be tested before commissioning and also in the periodical maintenance. In this paper, the performance of a var control relay (VCR) has been investigated. VCR controls the reactive power and if it be exceeded from allowed range, adjust the reactive power by connecting or disconnecting capacitor banks and consequently regulates the voltage. In this paper, first some important features of the VCR are explained and then some of these features have been tested, such as thresholds, the priority of signals, bank selection according to the switching counter and the performance of the relay against receiving protective signals. The results show that the relay operates correctly in different conditions.","PeriodicalId":314748,"journal":{"name":"2023 International Conference on Protection and Automation of Power Systems (IPAPS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127982309","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}

In this paper, the resonance between the grounding transformer and the phase-to-ground capacitor of the medium voltage output feeders of a sample subtransmission substation is investigated, considering that the phase-to-ground fault is interrupted.

The unconventional short-circuit behavior of inverter-based resources (IBR) challenges the conventional protective functions, causing spurious tripping for some external fault conditions and no tripping for some internal faults. An approach to alleviate the IBR protection issues is to develop new protective functions compatible with the fault response of IBRs. However, in a transmission system with high penetration of IBRs, many protective relays throughout the grid could be affected so that replacement of a large number of conventional relays is not practically feasible. Rather, it is economically beneficial to design the control system of IBRs so as to mimic the fault behavior of a conventional synchronous machine. This paper presents a current reference controller for the full-converter IBRs to utilize the maximum current capability of the inverter power-electronic switches while emulating the incremental sequence current magnitudes of a conventional synchronous generator. Conducting simulation studies in the PSCAD/EMTDC program, it is shown than the proposed method is well capable of achieving the mentioned goal for all fault types.","PeriodicalId":314748,"journal":{"name":"2023 International Conference on Protection and Automation of Power Systems (IPAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129669850","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}

Each DG contains a number of parallel units. The uncertainty due to planned or forced outage of the DG units changes the generation capacity, leading to overcurrent relays (OCRs) miscoordination in the distribution network. In this paper, new multiple optimal setting groups (SGs) are determined for OCRs that would satisfy protection coordination under various DGs capacity. In the first step, the proposed hybrid method uses k-means to classify different capacities of DGs into some clusters, whose number is equal to the number of SGs. The short-circuit current changes in each cluster; accordingly the OCRs coordination problems is modeled as an interval linear programming in the second stage, and optimal settings are determined for each setting group. The recommended technique is applied to the distribution section of the IEEE 14-bus system with two synchronous DGs. The outputs of the simulations and analysis have been done in PowerFactory and MATLAB software, respectively, indicate optimal coordination of relays for all DGs’ generation levels.","PeriodicalId":314748,"journal":{"name":"2023 International Conference on Protection and Automation of Power Systems (IPAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130859580","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}

Load shedding (LS) is one of the appropriate methods to reduce the destructive effects of FIDVR on the network, and for this reason, the authors have previously presented three LS methods to deal with FIDVR. The first method uses the index of IM loads’ power change. The second method is an optimization problem and the third method introduces indicators based on sensitivity analysis to find the location and amount of LS. The purpose of this paper is to examine the strengths and weaknesses of those three methods, and to determine each of these methods is suitable for use in what specific conditions. The proposed methods obtain less LS amounts, also, the number of LS locations and moments of proposed methods are fewer than previous ones. However, these methods have different execution times which are related to the speed of utilized processor, and a suitable method to deal with FIDVR must have the ability to shed the load in the initial moments of this phenomenon.","PeriodicalId":314748,"journal":{"name":"2023 International Conference on Protection and Automation of Power Systems (IPAPS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131664453","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}
