Development of an Algorithm for the Cascade of Vuoksin HPPs Automated Transfer to Parallel Operation with Nordel

The article analyzes the work and proposes the introduction of an automated transfer of generators to parallel operation with Nordel and their reverse return to parallel operation from the Unified Power System of Russia with the short-term inclusion of the Unified Power System of Russia and Nordel to parallel operation, which allows switching without stopping the generators and return them into idle speed.The conducted studies show the relevance and wide applicability of special automation, allowing to extend equipment life and minimize the reduction in power output that occurs when equipment is shut down.
