Wireless Monitoring of Power Plants: State Estimation by a Moving Horizon-Based Optimization Approach

摘要

Wireless sensor network (WSN) is receiving increasing attention in the Power Industry community because of a number of obvious advantages over wired cable, such as low cost, flexible installation and easy upgrade, to just name a few. To replace the wired systems via wireless ones, several technical challenges including, for instance, constrained communication capabilities, must be overcome. Due to wireless communication limits, sending data packets are subject to losses and delays. The purpose of this paper is to present a strategy that addresses the issue, by developing a wireless monitoring scheme for power plant systems that includes a data recover estimator. Under the assumption that the delivering rates from sensors satisfy certain conditions, the states of the power plant systems can be estimated by an online, moving horizon-based optimization approach. Plant control simulation results are given to illustrate the effectiveness of the proposed estimation and monitoring scheme.
