Pioneer Design of Noncontact Synchronized Measurement Devices Using Electric and Magnetic Field Sensors Traditional synchrophasors rely on CTs and PTs physically connected to transmission lines or buses to acquire input signals for phasor measurement. However, it is challenging to install and maintain traditional phasor measurement units in some remote areas due to lack of facilities. Since transmission lines naturally generate alternating electrical and magnetic fields in the surrounding atmosphere, this paper presents two innovative designs for noncontact synchronized measurement devices (NCSMD), including an electric field sensor based noncontact SMD (ENCSMD) and a magnetic field sensor based noncontact SMD (MNCSMD). Compared with conventional synchrophasors, ENCSMD and MNCSMD are much more flexible to be deployed and have much lower costs, making ENCSMDs and MNCSMD highly accessible and useful for a wide array of phasor measurement applications. Laboratory and field experiment results verified the effectiveness of the designs of both ENCSMD and MNCSMD.

Performance and energy efficiency of the analysis of the growing synchrophasor in a highperfomance computing environment Synchronized phasor (synchrophasor) measurements for power systems are is very useful tool for engineers in analyzing dynamic events in the grid which is not possible with traditional SCADA measurements and was codified in IEEE C37.118 Synchrophasor for Power Systems and IEEE 6025511812018 Synchrophasor for power systems  Measurements standards. Online and retrospective processing of data collected from hundreds and thousands of sources of synchrophasor measurements is a complex computational task. A Python based framework for digital signal processing with its parallel implementation was developed to use it in analysis of growing synchrophasor measurements. An implementation shows satisfactory performance and parallel scaling. The energyefficient regimes of its parallel execution were found. Ways of further optimization are identified. The results of numerical experiments are presented.
