In this work, a three-phase two-leg T-type active power filter topology is investigated when a three-level hysteresis band current modulation technique is applied. The three-phase two-leg T-type configuration which utilizes eight switching devices together split DC link capacitor banks is able to improve the reliability of the system as well as effectively reduces the power losses. The compensation of the current harmonics at each phase are achieved successfully with the control of phase-a and phase-b. Using this technique, the phase-c is directly connected to the midpoint of the split capacitors, which eliminates the necessity of additional control on the phase-c. …
Impact On Distribution System Protection With The Integration Of Eg On The Distribution Network, Jane Courtney, Aaron Mcdonnell
Impact On Distribution System Protection With The Integration Of Eg On The Distribution Network, Jane Courtney, Aaron Mcdonnell
Conference papers
A significant increase in EG connections on the distribution network over the past decade in Ireland has presented challenges to the Distribution System Operator (DSO). The connection of EG can cause co-ordination of Distance protection to be altered and has resulted in variations in short circuit levels. Multidirectional power flow has been introduced into a Distribution system that was not designed for the direction change in current flow. The impact of connecting EG to a typical 38 kV Distribution Network was demonstrated as part of this study. Increasing fault levels and protection co-ordination selectivity problems were identified when the network …
Series Compensation To Increase Power Flow: A Case Study On The Irish Transmission System, Aidan Heffernan, Jane Courtney
Series Compensation To Increase Power Flow: A Case Study On The Irish Transmission System, Aidan Heffernan, Jane Courtney
Conference papers
Ireland presents an interesting case study for transmission network strengthening. The majority of load in the country is located at the nation's capital, Dublin, in the East, while most of the new conventional generation and renewable generation are found in the South-West. Power is transferred between the two via a 400 kV network. This leads to large cross- country power flows. This power distribution disparity is due to increase. A large thermal generating station which is connected to the 400 kV system in the West, will close by 2025. This generation will be replaced partially with wind generation in the …
