Abstract：Based on time-optimal control (TOC) theory and auto-disturbance rejection control (ADRC) theory, emergency DC power support (EDCPS) control strategy is proposed with wide area signal measurement system (WAMS) signals. TOC theory is introduced to drive and fix system state to a post-fault new equilibrium point which based on integrated extended equal area criterion (IEEAC) can be approached on-line with WAMS signals, and finally auto-disturbance rejection control (ADRC) theory is introduced to trace the virtual control input. Simulation results of 6-machine-dual-infeed three-area system show that the proposed EDCPSCS can take advantage of quick DC power modulation and short-time overload capability to provide emergency control and power support and has a better control effect than that of traditional linear DC power modulation. ADRC owns characteristics of high adaptability and robustness in disturbance and model uncertainty, moreover, control effect aimed at the new equilibrium point is better than that aimed at the original one.
