Abstract

The invention discloses a wireless transmitting power prediction control method for reliability demand constraint of an intelligent substation, and the method comprises the steps: constructing a wireless signal propagation state space equation with state observation through the analysis of the relation among reliability, a signal-to-noise ratio and transmitting power and the utilization of a lossmodel and a Kalman filter of wireless signal propagation; performing expected signal-to-noise ratio compensation by estimating a confidence interval of signal-to-noise ratio fluctuation in real time;finally, defining a quadratic cost function taking the difference between the transmitting power and the actual signal-to-noise ratio and the expected signal-to-noise ratio as a target, and realizingoptimal control of the transmitting power through a dynamic programming algorithm. According to the invention, the problem of coordination between the transmitting power of the wireless sensor networkand the wireless communication reliability in the transformer substation environment can be solved, so that the transmitting power of the node is reduced as much as possible while the wireless communication reliability is ensured.
