This paper presents the results from a laboratory experiment of a single machine islanded area operated as a synchronous island. The paper also presents how this was realized as well as explaining the control theory that was utilized. The methodology given in this paper serves as a platform on which multi-machine islanding will be based. The laboratory setup consist of a generator model realized by...
Areas with only one connection to the transmission system are vulnerable to unintended blackouts after a failure. This paper describes two case studies. An area on the west coast of Norway has several large generators with frequency control capability to support the network. A challenge in this area has been to ensure continuous operation in case of switchover to island operation. The second involves...
This paper introduces a laboratory test-bench that is used to verify a novel wide-area load sharing scheme for synchronous islanding control. Many current mechanisms for islanding control rely on frequency droop. However, this approach does not provide optimal control as it is based on network conditions measured at individual generators with no input from any other parts of the network. The authors'...
This paper introduces a novel load sharing algorithm to enable island synchronization. The system model used for development is based on an actual system for which historical measurement and fault data is available and is used to refine and test the algorithms performance and validity. The electrical system modelled is selected due to its high-level of hydroelectric generation and its history of islanding...
