Power Quality Database Management and Power Quality Data Analytics

Abstract: Power quality (PQ) is an important issue for modern distribution systems which consist of many kinds of renewable energy sources such as PV, wind and biomass. The existing level of PQ is thus crucial for utilities for many aspects such as PQ improvement, PQ mitigation and solutions, system maintenance and planning, and benchmarking PQ. In order to perform such tasks, PQ database is required. The database should collect measurements from many substations in the system with effective management. Currently, Provincial Electricity Authority (PEA) is carrying PQ Database Management project. The first stage will be collecting measurements from all substations in PEA’s system and perform PQ data displays such as harmonics, flicker, unbalance, voltage sags. Minimum quality standard (MQS) and PQ health index will be proposed in the project. In the future, PQ data analytics will be implemented with available PQ data.
