Abstract

The development and applications of wide-area measurement system (WAMS) provide great potential for online assessment of voltage stability in large-scale power system. By using the WAMS to collect the measured value of local voltage and current vector directly, we can realize the online estimate and instruction of the voltage stability degree of key node. On the basis of the above reasons, this paper further researches the phase failure problem of slack node, puts forward that taking the voltage phase of the node, which has the nearest electrical distance from the slack node, as the reference phase, can also realize online correction of the voltage stability of the key node. The simulations show that this method is suitable for the surveillance of online static voltage stability of node and has certain feasibility.
