湖北实现首个10千伏山区微电网“黑启动”

Core Viewpoint - The successful "black start" test of a 10 kV rural distribution network in Hubei marks a significant technological breakthrough for enhancing grid resilience and smart energy transformation in rural areas [1][2] Group 1: Test Details - The "black start" command was executed in less than 100 milliseconds, restoring power to the previously disconnected area [1] - The test site, Hejiagou Village, has faced challenges due to a long supply radius of 14.23 kilometers since the 10 kV line was put into operation in 1987, leading to low voltage issues affecting residents [1] - The test demonstrated the ability of the distribution network to autonomously restore power and stabilize voltage and frequency after a complete outage [1] Group 2: Technological Advancements - The recent test is a continuation of Hubei Electric Power's exploration of grid-forming energy storage technology, achieving a significant improvement in power restoration speed from 33 minutes in June to milliseconds [2] - The previous test in Shayang validated the feasibility of grid-forming energy storage at the transmission level, while the recent test extends this capability to the distribution network, marking a transition from merely supplying electricity to providing high-quality electricity [2] - The test confirmed the technical feasibility of microgrid systems to operate independently and stabilize voltage under fault conditions [2]
