A strategy of nonsingular terminal sliding mode control is proposed for the voltage regulation system of DSEG(Doubly Salient Electromagnetic Generator). The structure of DSEG is described and its mathematical model is established,based on which,the operating principle of voltage regulator based on proposed control strategy is analyzed in detail and the corresponding sliding mode surface equation and sliding mode law are given. The control law parameters are calculated according to the constraint conditions of Lyapunov stability equation and the carrier wave intersection with fixed PWM control. A field-circuit cosimulation model is built based on the electromagnetic finite element analysis technique and the control circuit. The results of steady-state and dynamic simulations for DSEG show that,the voltage regulation system of DSEG based on the nonsingular terminal sliding mode control has excellent steady-state and dynamic performances,with small voltage ripple,short recovery time and little dynamic output voltage variation.

According to the structural characteristics of the disconnecting switches in GIS equipments,an online contact temperature monitoring method based on IR(Infra-Red) sensing is proposed. Highly emissive coating is spread on the contact surface to enhance its emissivity and the emissivity of infrared temperature sensor is adjusted to compensate the absorption effect of SF6. A GIS experiment platform is established and the influences of SF6concentration,IR filter and environmental temperature on IR sensing are researched. Experimental results show that,the indication of IR sensor reduces along with the increase of SF6 concentration,which could be compensated by lowering the emissivity of sensor. An online GIS contacts temperature monitoring system is designed based on the proposed method.

The requirements of intelligent breaker operation for signal processing are briefly introduced and the strong real-time conditions required by the intelligent breaker operation are given. IFFT(Improved Fast Fourier Transform) is applied in the algorithm simulation of rated current to reduce the calculation load.RLSCA(Recursive Least Square Corrective Algorithm) is applied to simulate the short circuit current,which enables the iteration method to be implemented on DSP with shortened sampling data window and meets the requirements of system for real time performance. A model is built with Simulink to simulate the process from normal working state to short circuit state and the total current signals are generated for two states respectively. Based on MATLAB,the short circuit current identification algorithm is simulated and,combined with IFFT and RLSCA,the total current signals are then simulated. Simulative results show that,the proposed algorithm meets the requirements of intelligent breaker operation for strong real-time performance.

Instead of the traditional linearization method used in APF(Active Power Filter) analysis,the discrete affine switching theory is applied in the modeling of three-phase APF with time-delay,based on which,its H∞controller and switching rules are designed. The harmonic current at grid side is regarded as the control output and the error between the instructive harmonic current predicted by feedforward control and the ideal instructive harmonic current is considered as the distracter to follow and control the harmonic current. Simulative results show that the proposed method reflects the dynamic characteristics of three-phase APF accurately while compensates the system time-delay effectively,avoiding its adverse influence on system compensation effect and stability.

A pricing model based on the long-term incremental cost method is proposed for calculating the wheeling cost of transmission network, which considers the influence of short-term operational cost on the investment time of transmission network components and the wheeling cost of transmission network. To simplify the analysis, the short-term operational cost considered is mainly the congestion management cost. The proposed model is applied respectively to the dual-bus test system and IEEE 30-bus test system, and compared with the traditional pricing model, which verifies its effectiveness.
