To suppress both the low-frequency oscillation and subsynchronous oscillation, the coordinated optimization strategy of the multi-channel PSS and TCSC Damping Controller is researched in this paper. Considering the oscillation modes to be suppressed as the objective modes, and the maximization of the damping ratio of the objective modes as the optimization objects, an optimization model is established...
Intermittent chaos will take place if the weak signal whose frequency is slightly different from that of the driving force of the Duffing oscillator. An array of oscillators is always used to detect signal of unknown frequency. By changing the common ratio and adding an addition test oscillator, the number of the oscillators is reduced from 79 to 40. A shifting cross zero point chain method is presented...
To assist dispatchers to on-line monitor small signal stability of power grid, this paper proposed an artificial intelligent method-Case-Based Reasoning(CBR) theory to predict small signal stability based on measurement data of wide area measurement system (WAMS). Oscillatory active power increment distribution (OAPID) was introduced to improve the prediction accuracy. The designing process of small...
This paper proposes a power system small signal (dynamic) stability early warning approach based on Case-Based Reasoning (CBR) theory, which is an artificial intelligent method. According to measurement data of Wide Area Measurement System (WAMS), this approach is able to achieve following functions: In normal operation status, it can estimate small signal stability of power grid via CBR in historical...
