Stability and Voltage Control

This course discusses the fundamental principles of stability and voltage and how these principles relate to real networks with distributed generation (DG).

You will learn about existing operational practices and the emerging need to refine these practices to address stability and voltage control issues resulting from the connection of additional DG to distribution networks.

This course will give you an understanding of a range of generator types and why they become unstable, types of instability, and how stability can be enhanced including stability studies and stability modelling.

Delegates will be able to apply their learning through a series of graded worked examples, created to represent actual rural and urban networks with various mixes of load, fault levels and numbers and sizes of DG.

  • Develop your ability to assess and enhance network stability
  • Enhance your ability to protect critical components on networks
