NR has designed hydropower unit protection solutions for the project and provided key equipment such as generator transformer unit protection and switchyard protection. Zungeru hydropower station is located in the middle and upper reaches of the Kaduna River near Zungeru Town, Niger, Nigeria. Wit...

On June 9th, 2018, a 500kV digital substation for the Bailing transmission and transformation project was successfully put into operation in Liangshan district, Sichuan, China. The Liangshan substation was the first 500kV digital substation commissioned by NR in the Liangshan district. all-around integrated solutions NR provided all-around integrated solutions for this substation, including network switches NR provided all-around integrated solutions for this substation, including intelligen...

NR successfully commissioned two sets of 20Mvar/13.8 kV Mobile Static Synchronous Compensator (STATCOM) in Layla and Summan Area, which is the world’s first energized fully mobile STATCOM. Due to large amount of induction-motor based air conditioner load the power grid of Saudi Arabian suffers from severe voltage stability and FIDVR issue (fault induced delayed voltage recovery). Dynamic Voltage Control STATCOM will provide dynamic reactive power compensation STATCOM is the most advanc...

NR is proud to announce the commissioning of India’s first 1 MW microgrid at the Central Electronics Limited (CEL) facility in Sahibadad, Uttar Pradesh, India. In over 10 years NR has deployed protection & control solutions around and pioneered the development of microgrid solutions. With the booming renewable energy integrated into India's power grid, it is a challenge to keep the stability of the power grid, due to renewable energy is not as stable as the traditional power supply. T...

On June 2nd, 2018, NR successfully commissioned two sets of 20 Mvar/13.8 kV Mobile Static Synchronous Compensator (STATCOM) in Layla and Summan Area, which is the world’s first energized fully mobile STATCOM. Due to the large amount of induction-motor-based air conditioner load the power grid of Saudi Arabia suffers from severe voltage stability and FIDVR issues (fault-induced delayed voltage recovery). STATCOM is the most advanced technology to mitigate voltage stability problems. STATC...

On May 25, 2018, Canada's 735 kV Chibougamau series compensation upgrade project undertaken by NR completed all field & commissioning tests without delay and successfully put into operation. Fundamentally, series compensators were installed in the 1990s in the Chibougamau Substation close to the James Bay Area by another supplier, its control and protection system has reached the end of its life span and the replacement of outdated spare parts is highly required. NR series compensators pro...
