Effect of Failure Scheduling Scheme to Reliability of Complicated Heat-Supply Network

The effect of failure valve-shut off scheme and limit heating to failure hydraulic regime and reliability of complicated heat-supply network was studied. Reliability index of three failure scheduling schemes in an actual heat-supply network was calculated. The results showed that it had better reliability to close only valves of water supply pipes or water return pipes with failure components than to close all valves of water supply pipes and water return pipes, and the reliability of limit heating is better than unlimited heating.
