This paper proposes a novel personnel positioning scheme for a tunnel network with blind areas, which compared with most existing schemes offers both low-cost and high-precision. Based on the data models of tunnel networks, measurement networks and mobile miners, the global positioning method is divided into four steps: (1) calculate the real time personnel(More)
This paper proposes a neuron adaptive harmonic detection algorithm which can adaptively,rapidly and precisely calculate the voltage and current reference signals in presence of the system frequency variation, according to which, a Double Integration Control (DIC) strategy is applied in Unified Power Quality Conditioner (UPQC) as an interface between the(More)
