Most electrical faults in distribution networks are single line to ground faults. If the energy impact at the fault location is minimized, the probability of ignition of dry vegetation can be significantly reduced. The fault current at single line to ground faults depends on the treatment of the neutral point. In ungrounded networks the fault current is determined by line to ground capacitance of the network. In compensated networks the main part of this capacitive current is compensated by an opposite directed inductive current, generated by a stepless adjustable coil between the neutral and ground. This coil is called a Ground Fault Neutralizer (GFN) [7], Arc Suppression Coil (ASC) or Petersen coil. In compensated networks only a small residual, mainly active current remains. This small fault current allows self-extinction of faults at overhead lines and continuation of power supply, if allowed by the grid code. The novel Advanced Residual Current Compensation (ARCC®) system together with a GFN can be used in such compensated networks to also rapidly compensate the remaining residual fault current and do so with high accuracy. The BoostPro® function additionally speeds up the residual current compensation. The ground fault itself can be detected with the admittance method, which works reliably also for high impedance ground faults. In case of changes of the network capacitance for example due to feeder switching operations, the GFN needs to be tuned quickly again, which is enabled by a new frequency adaptive trigger criterion.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125635961","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}

One of the main advantages of these inverters is their ability to operate in both grid-connected and islanded modes of operation. GFMs need to have a smooth transition between the different modes of operation to maintain synchronism during the transition and establish a stiff voltage source when in islanded or locked frequency mode. This paper presents a synchronization control technique based on smoothing the change in angle when the GFM transitions between modes of operation. Furthermore, a Power Oscillation Damper (POD) was designed as an auxiliary control of the GFM to damp electromechanical oscillations when operating in grid-connected mode. The proposed GFM model is interconnected to the modified IEEE 12-bus system, and simulation results demonstrate the effectiveness of the proposed control.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124845715","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 socio-patrimonial management of the resources must guard the integrity of the system, and it becomes essential to prevent occupation below the transmission lines. The radar images are viable alternative for the monitoring, being able to identify changes in the soil cover pattern without impediment from the clouds. In the scientific world these images have been better explored due to the costless and high frequency visits of the Sentinel-1. A scene dated year 2020 was chosen as default, spanning transmission line in the state of Ceará, Brazil and another scene, from 2021, was used to apply a change detection to check if the region remains unaltered or if there are patterns that correspond to new edifications. The application of change detection has shown to be feasible in the executed tests. Of the four spots of change, three of them have been confirmed. The process may be brought to its full potential with a larger number of scenes and samples with in loco verification.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125152212","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, where this pressure leads to the use of inferior components or installation methods, the safety outcomes will be impaired, and the whole of life cost may even be higher. This paper will explore the cost of various component groups in grounding systems of HV substations and lines, and present these in the context of both the asset and grounding system installation cost; and in proportion to the life-long cost of owning and managing the grounding system for a 30-year asset life.

An emerging issue plaguing electric utilities lie within the intersection of protection and performance grounding. These are strongly interrelated and conflicting subjects that dictate the occurrence of Temporary Overvoltage and the effectiveness of ground overcurrent protection. Currently, there remains a gap in the distribution planning of most jurisdictions in formulating these aspects and adopting simple and practical measures to balance these subjects. This paper develops a simulation-based method to develop a set of practical charts intended to be used as a sizing guideline for neutral grounding elements, which are to be employed in DER step-up transformers.

If they have adequate flexibility, hydropower plants are typically able to provide slower regulation support (e.g., Reg A in PJM), but do not respond fast enough to provide Reg D. The ability to provide Reg D would improve their revenue because this service is typically more valuable. This work presents a control approach to use hydropower, battery, and ultracapacitor systems to provide fast regulation in a way that uses the response contribution of each asset. In particular, the proposed control architecture applies a variational mode decomposition (VMD) technique on the incoming Reg D signal to extract multiple dynamic-regulation components with non-overlapping frequencies. With the response-speed dependent alignment, these regulation components are fed to the hydrogenator and hybrid energy storage system (HESS). The paper evaluates the proposed approach on a direct-current (DC)-coupled active system by computing several performance measures and analyzing sensitivity based on HESS component proportional capacities. The results reveal that the proposed VMD-based signal conditioning performs well and that optimizing the sizing of the battery and ultracapactor components further enhances performance.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125886631","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}
