The method includes detecting loss of voltage to the network, opening the source side switching device in the transformers nearest both ends of the power line, and detecting that voltage has been restored to the network. Also provided are a system and method for preventing distributed power generation export in a power distribution network during normal operation. The method includes determining the apparent power at the source side of each of the transformers, determining the apparent power at the load side of each of the transformers, comparing the determined apparent powers, and opening the source side and load side switching devices in any transformer where the determined apparent powers are not the same."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Anti-islanding protection and non-exporting tariff support","description":"A method for preventing unintentional islanding of loop networks when a distributed power source is providing power to the network when network power is lost.
