NR Successfully Commissioned 735kV Series Compensator Upgrade Project to Strengthen Eastern Canadian Power Grid
On May 25, 2018, Canada's 735kV Chibougamau series compensation upgrade project undertaken by NR completed all field & commissioning tests on time, and successfully put into operation.
The original series compensators were installed in 1990s in Chibougamau Substation closing to the James Bay Area by another supplier, its control and protection system has reached the end of their life span and the replacement of outdated spare parts are high required. NR 735kV Chibougamau system is an important project for the Quebec to improve the power transmission capacity of hydropower. The modernization of the control & protection system is expected to significantly improve the grid reliability and help reduce maintenance needs.
NR provides well-proven key equipment with independent intellectual property rights for this project, such as protection & control system, gap trigger system, measuring system and fiber signal column. In strict accordance with the Quebec electricity and technical requirements of series compensation control protection system, NR also carries out optical fiber signal column type experiment as required. Passed all strict factory , field & commissioning tests, NR series compensators project’s all technical indicators meet the requirements of Hydro-Québec (HQ), and have been highly evaluated.
Series compensation is a cutting edge technology that can reduce transfer reactance and increase the transient and voltage stability in transmission systems, most notably in bulk transmission corridors. This technology is part of NR's family of Flexible AC Transmission Systems (FACTS) solutions that increases the capacity and reliability of existing transmission networks, and contributes to the development of smart grids.
NR offers field proven HVDC & FACTS solutions to solve reliability and efficiency problems in power system. The complete HVDC & FACTS solution, along with high quality equipment, will help to increase transfer capacity and ensure quality of your next generation smart grid.
