G99 / Grid Code – Fault Ride Through (FRT)

G99 / Grid Code – Fault Ride Through / Fast Fault Injection Fault Ride Through studies are a basic requirement of Type B and C / D generators, to demonstrate ride through for a fault lasting 140ms. The basic process is the same in all cases, but the retained voltages and recover rate differs slightly […]

G99 / Grid Code – Reactive Power Requirements

For Type C / D Generation sites in the UK, one of the most important studies to carry out in the early stages of a project is a reactive power capability assessment. This study is a specific type of load flow case, used, to confirm that the equipment is correctly sized, and the site can […]
