“…If upward streamer discharges form on the sensors (especially the rod kind, and on those included in group III) of the monitoring system, frequencies that are in the spectrum of a current impulse (up to dozens or hundreds of megahertz) will be in the working frequency range of the sensor. This could lead to sensor failure, including errors in the digital processing of data by the analog-digital converters [11][12][13]29].…”

The results of a physical simulation using negatively charged artificial thunderstorm cells to test the spectrum of possible electromagnetic effects of upward streamer discharges on the model elements of transmission line monitoring systems (sensor or antennas) are presented. Rod and elongated model elements with different electric field amplification coefficients are investigated. A generalization is made about the parameters of upward streamer current impulse and its electromagnetic effect on both kinds of model elements. A wavelet analysis of the upward streamer corona current impulse and of the signal simultaneously induced in the neighboring model element is conducted. A generalization of the spectral characteristics of the upward streamer current and of the signals induced by the electromagnetic radiation of the nearby impulse streamer corona on model elements is made. The reasons for super-high and ultra-high frequency ranges in the wavelet spectrum of the induced electromagnetic effect are discussed. The characteristic spectral ranges of the possible electromagnetic effect of upward streamer flash on the elements of transmission line monitoring systems are considered.

“…As described in [10], graph methods can be integrated to derive the changes in the TNTP. As proposed in [11], novel wireless sensor network can be establish to identify the branch status, which can be used to derive the TNTP. Thus, an improved TNTP or an validation for the existing TNTP is required.…”

Power system transmission network topology is utilized in energy management system applications. Substation configurations are fundamental to transmission network topology processing. Modern power systems consisting of renewable energy sources require reliable and fast network topology processing due to the variable nature of wind and solar power plants. Currently used transmission network topology processing, which is based on the relay signals communicated through SCADA is not highly reliable or highly accurate. Substation configuration identification (SCI) for different substation arrangements including main and transfer bus arrangement (MTBA), ring bus arrangement (RBA), and single bus arrangement (SBA) is investigated. Synchrophasor measurement based SCI for functional arrangements (FA) using artificial intelligence (AI) approaches is proposed in this paper. This method improves monitoring FA. Typical results for MTBA, RBA and SBA substation configuration identification is presented. A modified two-area four-machine power system model with two grid connected solar PV plants consisting of MTBA, RBA and SBA is simulated on real-time digital simulator. AI based SCI is shown to accurately identify all possible FAs for the three substation arrangements under any operating condition.

“…The authors of [15] developed a clustering algorithm to balance the network's energy consumption and a hybrid media access control protocol to handle traffic variability. In [16], a hybrid transmission line monitoring network was investigated, where different types of communication technologies were utilized in the hierarchical network. The work of [11] presents accurate probability distribution models for topological and geometrical parameters for WSNs in transmission line monitoring.…”

Robust Online Overhead Transmission Line Monitoring With Cost Efficiency in Smart Power Grid

In this work, we investigate a cost-efficient strategy to implement robust online overhead transmission line monitoring for stable energy transfer in smart power grid. As a first step, we first present an analytical framework to evaluate communication performances of wireless sensor networks installed for the real-time monitoring of overhead power transmission line, wherein each tower performs fountain code (FC)based transmission for guaranteeing transmission reliability between each tower and a substation. Then, we evaluate communication performances given in terms of successful FC-based transmission probability and its end-to-end delay for each tower. Further, our analysis helps formulate an optimization problem that aims at minimizing the total number of activated wide area network (WAN) communication modules deployed on towers(i.e., minimizing the total monetary cost required to use WAN communications), while simultaneously supporting three different types of communication quality of service (QoS) requirements (e.g., reliability, delay, robustness).To find the solution of the problem, we propose the Path Decision in the order of the Farthest Towers (PDFP) algorithm, which enables to find a suboptimal-solution of the problem in real-time. The key idea of PDFT algorithm is that paths (i.e., whether to use a WAN communication module) are sequentially determined in the order of towers farthest from the substation. To identify the validity of the proposed algorithm, we conduct performance evaluations with using public topological and geometrical information of an actual national power grid in Korea. Performance evaluation results show that the proposed PDFT algorithm can find towers that need to activate their WAN communication modules for guaranteeing diverse QoS requirements in real-time, as compared to an optimal-solution algorithm without significant difference in total number of activated WAN communication modules.
