On January 31, 2020, the first digital substation integrated with NR PCS-S products was officially put into commercial operation in Concordia, Ecuador.
The project integrates NR latest generation of protection & control products, including PCS-931S Line Differential Relay, PCS-915S Busbar Relay, PCS-221S Merging Unit and PCS-9700 SCADA system etc.
Interconnection of the large power grid
As a key project in TRANSELECTRIC Ecuador, the project successfully realizes the interconnection of the large power grid in Western Ecuador and further increases the reliability and stability of power supply in coastal cities.
The project adopts IEC62439 (PRP) and IEC61850 Ed2 communication protocol, which successfully solve the problems of digital network redundancy and compatibility with third party products.
Requirements for digital substation
NR Electric will continue to deliver high-quality guard automation control systems to global customers
PCS-9705S Bay Control Unit integrates PMU function, realizes the operation & maintenance requirements of automatic switching of AC & DC systems, intelligent alarm of communication network, and automatic switching of protection function through powerful logic and analog programming.
After a detailed test by the customer's engineer, all the functions meet the Ecuadorian power grid operation regulations.
The successful operation of La Concordia digital substation marks that PCS-S series products have the advanced application to fulfill the requirements for digital substation. NR Electric will continue to deliver high-quality protection automation control systems to global customers.
Advanced PRP redundant communication technology
The site that used the NR-experienced digital substation solution has reduced a lot of wire cable in the switchyard, and it will also save the substation maintenance costs in the future.
At the same time, advanced PRP redundant communication technology and the NR new platform of high-performance products used in the system provide a strong safeguard to users and ensure the stable and reliable operation of the substation.
It is a good case study for our customer in South America, and it will set a good example and a good template effect for the Ecuador electricity market.
