Development of improved power quality detection methods suitable for modern applications

Discontinuities of service, variations in voltage magnitude, and distortions in AC voltage waveforms constitute the different aspects poor power quality. A poor quality of power supply can cause malfunction of sensitive equipment and interrupt industrial processes, resulting in significant economic losses. Utilities and consumers are taking actions to maintain the power quality set by the standards. Monitoring of power quality at all levels in the power system is necessary to ensure adherence to standards, but specialized power quality monitoring equipment are expensive.

Communication assisted hybrid overcurrent-transient directional protection scheme for active distribution networks

With worldwide efforts to increase the utilization of renewable energy, traditional power distribution networks are being transformed into active distribution networks with the interconnection of distributed generation. The status of DGs connected to an active distribution network can change frequently, and this creates many challenges to network protection. The aim of this project is to implement a new protection solution for active distribution systems and microgrids in hardware and validate its performance.

Monitoring power system small-signal rotor angle stability under ambient operating conditions

An electrical power system is designed to provide safe and reliable supply to customers. However well designed the system, disturbances are unavoidable during the operation and the system should be able to continue secure operation. In fact, if it can be early determined that the system is moving towards an unsecure region, the operators can take necessary safety actions to keep the system secure. Thus, the main goal of this study is to develop novel techniques to monitor the stability of an electrical power system in real time.

Wide-area synchrophasor measurements based power system stability enhancement

The ability of observing the dynamics of an interconnected power system spread over a large geographical area in real time using synchrophasor technology enables the design of power system controllers against system wide disturbances which could lead to catastrophic failures. Currently, the synchrophasor technology is primarily used for monitoring applications and its potential for using in protection and stability control is not fully utilized.
