| 2 | A review on synchrophasor communication system:communication technologies,standards and applications显示文摘The present-day power system is a complex network that caters to the demands of several applications with diverse energy requirements.Such a complex network is susceptible to faults caused due to several reasons such as the failure of the equipment,hostile weather conditions,etc.These faults if not detected in the real-time may lead to cascading failures resulting in a blackout.These blackouts have catastrophic consequences which result in a huge loss of resources.For example,a blackout in 2004 caused an economic loss of 10 billion U.S dollars as per the report of the Electricity Consumers Resource Council.Subsequent investigation of the blackout revealed that the catastrophe could have been prevented if there was an early warning system.Similar other blackouts across the globe forced the power system engineers to devise an effective solution for real-time monitoring and control of the power system.The consequence of these efforts is the wide area measurement system(WAMS).The WAMS consists of several sensors known as the phasor measurement units(PMUs)that collect the real information pertaining to the health of the power grid.This information in the form time synchronized voltage and current phasors is communicated to the central control center or the phasor data concentrator(PDC)where the data is analyzed for detection of power system anomalies.The communication of the synchrophasor data from each PMU to the PDC constitutes the synchrophasor communication system(SPCS).Thus,the SPCS can be considered as the edifice of the WAMS and its reliable operation is essential for the effective monitoring and control of the power system.This paper presents a comprehensive review of the various synchrophasor communication technologies,communication standards and applications.It also identifies the existing knowledge gaps and the scope for future research work. | Bhargav Appasani Dusmanta Kumar Mohanta | 2018 | Protection and Control of Modern Power Systems2018，3，1： | 1 |

| 5 | Augmentation of situational awareness by fault passage indicators in distribution network incorporating network reconfiguration显示文摘Power distribution systems are profoundly inclined to disturbances like untimely switching of breakers & relays, sympathetic tripping, and uncertainties regarding fault location. Thus, system stability and reliability are greatly affected. In this way, situational awareness and system integrity are the crucial factors in developing power system security, as it empowers successful decision making & timely reaction by the operators to any disturbance and also maintaining continuity of power supply. This paper focuses on the enhancement of situational awareness by fault location through fault passage indicators (FPI) to improve nominal impedance-based methods in distribution networks. Also, the proposed method is validated by comparing it with Intelligent Electronic Device (IED) based fault location method. Further, simultaneous reconfiguration of the system is incorporated to maintain the continuity of supply. The analysis has been tested on IEEE 33 bus distribution system. | Tanmay Jain Debomita Ghosh Dusmanta Kumar Mohanta | 2019 | Protection and Control of Modern Power Systems2019，4，1： | 1 |
| 6 | Shifting of research trends in islanding detection method-a comprehensive survey显示文摘The augmentation in electricity demand,power system privatization as well as efficacy of renewable resources has paved the way for power system companies and researchers to exploit the field of grid connected distributed generation(DG)and its issues,islanding being a dominant one.Several research works have been conducted to mitigate the issues of islanding detection(ID).In context of this,the paper gives a comprehensive review of islanding issues,standard test systems,criteria and shifting of research trends in islanding detection methods(IDMs).The significant contributions pertain to categorization of IDMs,evaluation of non-detection zone(NDZ)for each test system,disquisition on evolution and advancement of IDMs and its comparisons based on criteria such as NDZ,run on time,nuisance tripping percentage,applicability in multi DG system and implementation cost to draw out the strength and shortcomings of individual methods that will come to aid to the companies or researchers for establishing the applicability and appropriateness of such method for their concerned domain. | Soham Dutta Pradip Kumar Sadhu M.Jaya Bharata Reddy Dusmanta Kumar Mohanta | 2018 | Protection and Control of Modern Power Systems2018，3，1： | 1 |
| 7 | Remote monitoring system for real time detection and classification of transmission line faults in a power grid using PMU measurements显示文摘Remote monitoring of transmission lines of a power system is significant for improved reliability and stability during fault conditions and protection system breakdowns.This paper proposes a smart backup monitoring system for detecting and classifying the type of transmission line fault occurred in a power grid.In contradiction to conventional methods,transmission line fault occurred at any locality within power grid can be identified and classified using measurements from phasor measurement unit(PMU)at one of the generator buses.This minimal requirement makes the proposed methodology ideal for providing backup protection.Spectral analysis of equivalent power factor angle(EPFA)variation has been adopted for detecting the occurrence of fault that occurred anywhere in the grid.Classification of the type of fault occurred is achieved from the spectral coefficients with the aid of artificial intelligence.The proposed system can considerably assist system protection center(SPC)in fault localization and to restore the line at the earliest.Effectiveness of proposed system has been validated using case studies conducted on standard power system networks. | Pathirikkat Gopakumar Balimidi Mallikajuna Maddikara Jaya Bharata Reddy Dusmanta Kumar Mohanta | 2018 | Protection and Control of Modern Power Systems2018，3，1： | 1 |
| 8 | PMU based adaptive zone settings of distance relays for protection of multi-terminal transmission lines显示文摘This paper proposes Phasor Measurement Unit(PMU)based adaptive zone settings of distance relays(PAZSD)methodology for protection of multi-terminal transmission lines(MTL).The PAZSD methodology employs current coefficients to adjust the zone settings of the relays during infeed situation.These coefficients are calculated in phasor data concentrator(PDC)at system protection center(SPC)using the current phasors obtained from PMUs.The functioning of the distance relays during infeed condition with and without the proposed methodology has been illustrated through a four-bus model implemented in PSCAD/EMTDC environment.Further,the performance of the proposed methodology has been validated in real-time,on a laboratory prototype of Extra High Voltage multi-terminal transmission lines(EHV MTL).The phasors are estimated in PMUs using NI cRIO-9063 chassis embedded with data acquisition sensors in conjunction with LabVIEW software.The simulation and hardware results prove the efficacy of the proposed methodology in enhancing the performance and reliability of conventional distance protection system in real-time EHV MTLs. | Balimidi Mallikarjuna Pudi Shanmukesh Dwivedi Anmol Maddikara Jaya Bharata Reddy Dusmanta Kumar Mohanta | 2018 | Protection and Control of Modern Power Systems2018，3，1： | 0 |
