Abstract:
Monitoring of natural gas transmission networks, is one of the necessities for efficient, safe, and economical operation of energy supply networks. In order to efficiently control and monitor the operation of gas transmission network, various states of the network (like temperature, pressure, and flow) should be available. Among these states, some can be easily measured, and the rest should be estimated based on these measurements throughout the network. In this project, an algorithm to obtain near optimal locations of various measuring devices has been proposed. Furthermore, a method for estimation of the states of transmission network based on these measurements and Machine Learning has been obtained. The results show that the proposed algorithm is capable of capturing important states of the system based on which the performance of the network can be monitored and controlled. Various type of Neural networks have been used in the state estimation and their performances have been compared against each other
