Modern approaches to estimation of power quality
One of the most important properties of the electric power system is its observability. Ensuring observability is relevant not only for power flows and reliability indicators of power supply, but also for power quality indicators, in particular, the non-sinusoidal shape of the supply voltage.

| description | One of the most important properties of the electric power system is its observability. Ensuring observability is relevant not only for power flows and reliability indicators of power supply, but also for power quality indicators, in particular, the non-sinusoidal shape of the supply voltage. Increasingly, the use of elements of power electronics in intelligent power systems, and its application will grow in the future. This leads to the appearance of harmonic components of higher orders of current and voltage. The objects of the power system can be either sources or receivers of harmonics. In this regard, the actual task is to assess the impact of individual objects on the quality of electrical energy in the power system. The observability of Проблемы энергетики, 2017, том 19, № 7-8 86 power systems can be realized by the application of the phasor measurement units (PMU). In this paper, the authors suggest using a distributed system for monitoring the power quality by using the existing PMU infrastructure. This will allow for continuous monitoring of the level of harmonic oscillations in different sections of the power system. Especially this event should be used for isolated power supply systems. |
