By presetting action logics, these automated devices can quickly isolate faults and restore outage loads. In order to meet resilience requirements, the non-automated distribution network should be upgraded to a partially-automated one due to limited budget. Conventionally, such resilience reinforcement plan is designed based on engineers’ experience. In this paper, we propose an optimization model for optimally upgrading manually operated switchable equipment to automatically operated one by local feeder automation in distribution networks, in which the predefined resilience indices for networks are explicitly expressed as constraints. The control logics and coordinated operations of feeder automation equipment are analytically formulated. Finally, the proposed model is formulated as the mixed-integer linear programming (MILP) and can be effectively solved. Case studies on an 8-section illustrative system and a 54-node system show the effectiveness of the presented models.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"927-937"},"PeriodicalIF":3.8,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PD measurement is particularly relevant in the area of cable accessories, as both the cable joints and the cable terminations are the most frequent cause of faults within the cable system. Among other things, this can be traced back to assembly faults or improper work. Ultra-high Frequency (UHF) PD measurement is becoming more important in the field of cable terminations. This contribution shows how an on-site measurement can be performed on various 110-kV-cable terminations with a self-developed UHF system. The UHF-PD tests were carried out in two substations. In the first substation, the tests were performed under AC operating voltage on a total of six cable terminations. With the UHF system, both corona discharges and surface discharges could be reliably detected. In the second substation, the UHF PD test was performed in combination with a commissioning test with Damped AC-Test Voltage (DAC). During the commissioning test, PD activity was detected on phases L2 and L3, both in the area of the cable termination. The results of the UHF system confirm those of the conventional PD measurement performed in parallel.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"1169-1179"},"PeriodicalIF":3.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143443531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, an OWF model, which includes the SR model with distributed parameters and the VCB model considering arc reignition, is implemented in the environment of electromagnetic transient program (EMTP). Based on the theory of waveguide, the voltage distribution along the SR winding is analyzed. The influence of reignition number on the oscillation of voltage distribution is discussed. Then, the method for evaluating the strength of overvoltage cumulative effect is proposed based on the <italic>U</i>-<italic>N</i> curve of insulation breakdown. The results indicate that the weakness of insulation breakdown usually occurs in the middle of the winding. The performances of three overvoltage suppression measures in reducing cumulative effect are compared.

Sub/super-synchronous oscillations (SSOs) and high-frequency oscillations (HFOs) have been frequently reported globally, prompting the implementation of numerous control strategies aimed at mitigating these oscillatory events. However, in more complex systems, such as multi-infeed MMC-HVDC systems, there exists the potential for multi-mode oscillations, which refers to the concurrent occurrence of multiple independent oscillation components at a single electrical node. This novel oscillation issue in multi-infeed MMC-HVDC systems is still lack of relevant research. To address this issue, an analytical approach using whole-system impedance analysis alongside a parameter sensitivity index is employed to investigate multi-mode oscillation phenomena in a multi-infeed MMC-HVDC system. Furthermore, an adaptive control strategy based on fast oscillation frequency detection is proposed, which demonstrates effectiveness across various operation conditions through case studies.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"1203-1213"},"PeriodicalIF":3.8,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143417171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test circuit combines the high current part from the synthetic test circuit as per IEC Std. 62271-101 with the so-called Rabus high voltage part. The high current part reproduces the current phase before voltage build-up occurring after zero current crossing, then the Rabus high voltage part provides voltage breakdowns constituting breakdown voltage characteristics. The high current part can be adjusted to represent the actual current conditions which influences the physical conditions of the contact system upon which the interruption process is highly dependent. To illustrate the measuring system and the measuring procedure, the measurements of the breakdown voltages are reported for a commercial 12 kV/1250 A/31.5 kA vacuum circuit breaker. The breakdown voltages are measured primarily as a function of time and then converted via a contact travel curve into the vacuum interrupter contact gap function. This allows the results to be converted back and applied to a breaker with the same characteristics of the vacuum interrupter unit operating in similar current conditions, but with different mechanical characteristics of the breaker-specific actuator than the one used in testing.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"1214-1222"},"PeriodicalIF":3.8,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When an earth fault occurs on the multi-earthed TN-C system, the fault current passes through the combined protective and neutral (PEN) conductor back to the source, resulting in a low residual current. However, unbalanced load switching also generates residual current through the same path back to the source, thus making fault discrimination very difficult. To address this problem, the four-wire multi-earthed TN-C system was analyzed by decoupling the mode 0 and the mode N of the equivalent circuit so that the current characteristics can be clearly studied. A new earth fault detection method is developed which compares the residual current deviation with the PEN conductor current deviation. The scheme uses amplitude ratio and phase angle difference between these two measurements to discriminate between earth faults and unbalanced load switching. The feasibility of the proposed method was verified by digital simulation and by physical tests in an actual LV distribution network. Compared to approaches based only on residual current, the proposed method demonstrates better sensitivity and reliability.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 2","pages":"1191-1202"},"PeriodicalIF":3.8,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143417169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
