Power was cut to large areas of the North Island on Tuesday 13th December 2011 by a fault at the 1448 MW Huntly power station. While the cause of the problem is not known (at the time of this news item) its effect was widely felt by power being suddenly disconnected to more than 200,000 consumers in areas from Wellington to Auckland and further north. The incident triggered load shedding to retain the balance between generation and demand and to protect the national grid from collapse. Quasar’s FCAS application is installed at numerous locations around NZ and captured the 47.6Hz event. The resulting information shows the grid frequency immediately prior to the event and for the period following. This post period shows the connected generation’s response to the event as it begins to recover the frequency to 50Hz.

The Energy Efficiency and Conservation Authority (EECA) has recently installed a Quasar energy management system in their Wellington offices, to demonstrate the value of monitoring energy use. The system features an energy monitoring display using PowerLogic ION Enterprise software, which gathers, analyses, stores and displays all energy data in a user-friendly format. The display provides an easy, cost-effective way of tracking energy use in the offices and saves on administrative costs as no manual meter reading is involved. It has also been tailored to allow EECA to compare energy use between its two different office floors. Mike Underhill, Chief Executive, says the system allows EECA to identify opportunities to refine existing energy saving measures and demonstrate the potential for improving energy use in an office environment. “The energy monitoring display has enabled EECA to identify a series of small improvements that combined add-up to a noticeable saving year on year. The project also provides a valuable demonstration model that can be viewed by commercial building owners or tenants.” Anyone interested in viewing the system should contact Senior Relationship Manager Mike Bourke at EECA, email mike.bourke@eeca.govt.nz or phone (04) 470 2227. PowerLogic ION Enterprise software is a complete power management solution for energy providers and industrial or commercial operations. Learn more? |
