DIgSILENT Pacific appointed for Upper North Island Reactive Power Investigation

DIgSILENT Pacific has been appointed by Transpower NZ Ltd, the national grid owner and operator in New Zealand to undertake a dynamic reactive power investigation for the upper North Island. The project involves considering the impact of varying dynamic motor load on the short term voltage stability in the region. Time domain simulations are required to assess short term voltage stability and the project must assess the impact of various planned grid expansion projects and make recommendations for dynamic reactive support to maintain voltage quality within Transpower standards.
