Topic:"System Reliability" in M13016

Why do this project? This equipment experienced in-service failures and needs to be replaced to ensure the continued reliability of the system at the 101S and 79N substations. The loss of these reactors limits the ability of the Control Ce...

AI summary The project is necessary to replace equipment that has experienced in-service failures at the 101S and 79N substations. This replacement will ensure system reliability and improve the Control Centre's ability to manage voltages, especially during low load conditions. Adding a system spare reactor will also enhance system resiliency.

Why do this project now? This project needs to be completed now because the NS grid cannot be operated in an optimal fashion when these components are out of service. These reactors are used to absorb reactive power and reduce system volta...

AI summary This project must be completed now because the absence of certain grid components, such as reactors, forces the system operator to use less desirable methods to control voltage. These alternatives include increasing reactive power flow, delaying outages, and running voltages higher than desired, which negatively impact system reliability and power quality.
