Abstract

Abstract: In order to improve work safety ability of unmanned hydropower stations, preventive measures and emergency response strategies in the face of abnormal states were studied from the perspective of operation risk. Firstly, nine kinds of operation risks under extreme conditions and unattended conditions were identified and analyzed according to production characteristics of the stations. Secondly, based on their operation management mode, corresponding risk prevention measures were proposed to ensure the safety of "dam-plant-equipment-person". Finally, with three defense lines of "system autonomy, remote assistance and on-site command" as the core, emergency response process was designed and risk classification control mechanism was established before they were verified through a case study on Shenxigou unmanned hydropower station. The results show that to analyze risks and design preventive and response measures based on characteristics of hydropower production and management mode are very helpful in improving standardization level of risk prevention and control for unmanned hydropower stations considering systematic risks caused by extreme factors.

Key words: unmanned hydropower station, operation risk, identification and analysis, risk prevention, emergency response
