The excitation control systems of large synchronous generators have a great impact on both the static stability and dynamic stability of power systems. This paper mainly focuses on the influence of elevating excitation system ceiling voltage ratio (ESCVR) towards system's transient stability by simulation works. Examples show that increasing ESCVR of a generator would be able to improve the transient...
Voltage stability margin of regional network is not a fixed quantity but closely related to operation condition and operation constrains. This paper proposes an effective method to estimate the real-time voltage stability margin based on some locally synchrophasor measurements. A Radial Basis Functions (RBF) neural network is employed to estimate the regional margin. The validity of the method is...
