Reactive Compensation Studies are conducted to identify and provide possible solutions to voltage control and fluctuation problems. These studies analyze the cause and effect of high or low voltages, dynamic swings and voltage flickers on systems and provide a wide range of technical solutions to resolve these issues.

Teshmont's staff have been analyzing voltage control problems for power transmission systems throughout the world for over thirty years. Teshmont has the expertise to identify issues and their sources quickly and will help you to eradicate their costly impact on your system.

In a typical reactive compensation study Teshmont will:

• Identify the voltage control problem
• Trace the source of the problem
• Provide viable solutions and options:
  • Operating restrictions
  • Passive controllers - shunt capacitors and shunt reactors
  • Dynamic controllers - SVC's: thyristor controlled reactors, thyristor switch reactors and other FACTS Devices
• Determine cost estimates of these solutions and options
• Preparation of a comprehensive and easily decipherable report

Benefits you will gain from using Teshmont to conduct a Reactive Compensation Study:

• Past experience and knowledge from proven experts
• Reduction of the time required to complete analyses and determine options
• Reduction of the risk of system failure
• Enhancement of system performance and financial return

For examples of Teshmont services in this area, please refer to the Three Gorges - Changzhou 3000 MW HVDC project where voltage control was critical to ensure that this system, which covered 3 regions in China, would not fail. Teshmont also developed software to help control low short circuit levels in the Gull Island Transmission Facilities project in Labrador, Newfoundland.
