Study on transient electric shock characteristics between human body and metal clothes hanger on residential platform near UHV AC transmission lines

IET Generation, Transmission &Distribution, Volume 18, Issue 22, Page 3646-3656, November 2024.
A full‐size steel‐framed residential test platform was constructed near a 1000‐kV ultra‐high‐voltage AC transmission line, then the performances of transient electric shocks when human bodies contacting a metal clothes hanger were investigated. The transient shock current characteristics and correlation between transient shock energy and human ...

An artificial intelligence‐based non‐intrusive load monitoring of energy consumption in an electrical energy system using a modified K‐Nearest Neighbour algorithm

IET Smart Cities, Volume 6, Issue 3, Page 132-155, September 2024.
Non‐intrusive load monitoring, prediction and forecasting. Abstract Energy profligacy and appliance degradation are the apex reasons accounting for the continuous rise in power wastage and high energy bills. The decline in energy conservation and management in residences has been largely attributed to the financial implications of using intrusive ...

Reduced‐order electromagnetic transient model based on equivalent flux linkage derivative for induction motors under voltage sag condition

IET Electric Power Applications, Volume 18, Issue 6, Page 693-703, June 2024.
An improved third‐order model that can accurately reflect the behaviour of IMs during voltage sags based on equivalent flux linkage derivative is proposed. The simulation and experimental results show that the proposed model realizes relatively high accuracy and short simulation time.

Lumped‐element equivalent circuit modelling of district heating pipe in electromagnetic transients program

The Journal of Engineering, Volume 2024, Issue 4, April 2024.
A lumped‐element circuit model of district heating (DH) pipe considering heat loss, transfer delay and enthalpy transfer is proposed. The proposed model has a high level of accuracy and is computationally more efficient than the existing distributed‐element circuit model of pipe. The lumped‐element circuit representing the DH pipe has only two nodes by
