Abstract

With the implementation of smarter grids, more Intelligent Electronic Devices (IEDs) is likely to comply with the IEC 61850 communication protocols in order to interact with each other seamlessly using GOOSE messages to exchange information amongst devices. In this paper, IEC 61850 messaging scheme will be proposed in one of the voltage control devices i.e. On-Load Tap Changer (OLTC) transformer to solve the interaction problem amongst the in-series OLTCs caused by a voltage disturbance in the distribution network. An improved fuzzy logic control scheme is also investigated in this paper to overcome the interaction problem. This will be preceded by review of existing schemes used for tap changer control.
