Reactive Power Management Presented By International Expert

Reactive power management is gaining importance as network systems become more heavily loaded. Capacitive support is effective to a point, but offers limited voltage control and may actually mask impending voltage collapse. Dynamic compensation overcomes those limitations, but at increased cost.

Furthermore, voltage control issues are arising on weaker subtransmission systems, due to a variety of factors that include proliferation of air-conditioning loads, and remote connection of wind generation and mining loads.

The course will establish a clear understanding of the basic concepts and issues underlying reactive power support and voltage control.

It will present methods for analysing static and dynamic voltage phenomena, and relate those methods to reactive power security margins.

The capabilities of various voltage control technologies will be explored, and a comparison of static versus dynamic reactive support provided.

The course will describe measures for correcting reactive power deficiencies following major disturbances. The impact of wind generation and large load fluctuations will be considered, along with methods for mitigating the associated voltage problems.
