The objective is to determine the effectiveness of D-SVCs controlled by the D-VQC, along with an advanced tap changer relay, to control voltage on an 11kV rural network. In this phase, 3 D-SVCs will be connected across the 11kV network of a single primary substation; 2 D-SVCs on the same feeder where there are multiple generators, the 3rd on another feeder adjacent to a larger generator. This will test the ability of the D-VQC to optimise two D-SVCs in close proximity while using all three along with the tap changer relay to keep the voltage as stable across the network.

- Optimise multiple networked D-SVCs on the distribution network

- Identify the appropriate impedance transformer and establish its sensitivity to the voltage control- Develop a communication system for rural 11kV networks

- Implement a pole top sensor that measures real power, reactive power and voltage

- Integrate control and data from the D-VQC and D-SVC systems into ENMAC/PowerOn Fusion

- Develop a tap changer relay scheme that integrates with the D-VQC
