This paper proposes a new computer network-facilitated voltage stability control strategy for electricity power distribution systems connected with distributed generations. The proposed strategy aims to determine stability enhancement operations on two aspects: one is to increase power system operation security during normal conditions, and the other is to save a distribution system from imminent voltage collapse due to contingencies. The operations include coordinated local generating, load tap changing, load shedding, etc. This paper shows the use of state-of-the-art digital signal processing technology for determining correct operation security enhancement and voltage instability controls, and the application of modern computer networking technology for monitoring of distribution system operating states and transmitting of data and stability control commands. This paper presents the design of a new architecture for network monitoring, data transmitting, and control delivering. This architecture is fault tolerant and is specially designed for monitoring distribution systems with multiple (over hundred) feeder nodes.
