| Objectives | 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 | |
| Abstract | As integration of Distributed Generation (DG) into the distribution network becomes more common, the growing number of connections to distribution lines can cause voltage problems. These can be either high voltage during power output or low voltage during times of high demand and low generation due to the variable power output of the DG as majority of DG is weather-dependent. Both of these voltage problems can cause the voltage move outside statutory voltage limits but also cause large variation in the voltage profile. In turn this can affect the efficiency and capacity of the distribution network to connect further DG or demand. There are several different ways that the voltage on rural network can be controlled to reduce this variation. However, some traditional solutions are unable to cope with the rapidly varying output of renewables such as wind turbines and photovoltaics (PV). Additionally D-SVCs can be deployed across various locations of the 11kV network connected to a primary substation to optimise the voltage locally close to the problem. With this combined with the ability to influence primary bar voltage from remote measurements the entire system voltage can be control within tighter limits. In this project we intend to build on the learning of the first phase by increasing the number of D-SVCs connected into to the same 11kV network and integrate their control with a D-VQC. This allows voltage optimisation across that entire 11kV network. To do this effectively multiple measurement points need to be introduced onto the system. Therefore an effective, high bandwidth communication network to connect the measurement points and control the D-SVCs needs to be incorporated to cover remote spread of the 11kV network. The D-VQC will be integrated with a more sophisticated tap changer relay at the primary substation which will aid the voltage optimisation by changing the bar voltage to ensure that there is not voltage infringements on all the feeders. This will take account of the generation output of individual feeders but also the level of demand on the others. One of the key learning points from the first phase was that WPD’s standard transformer which was used to connect the D-SVC, however its performance was limited as they were not impedance matched. In this second phase there will be additional work to ascertain the ideal transformer impedance and how much of an impact this has on the effectiveness of the D-SVC to control the 11kV voltage. This will be carried out in lab conditions on a test network to reduce the effect of other factors.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
