Studies on the tie-line power control with a large scale wind power

According to the tie-line power fluctuations in the influence of a large-scale wind power, an effective control strategies and methods are proposed in this article, that is the coordination control of on-line phase and the pre-control phase, the coordination control of the NON-AGC units, AGC and NON-AGC units. And on this basis, a corresponding mathematical model is established. The actual performance of the AGC unit, non-AGC unit, thermal Power and hydropower are fully considered in the model. The proposed method and model have a guiding significance to the dispatching operation where there is a large scale wind power.

Insulation characteristics analysis of the spacer with the temperature sensor

To study the effect of the temperature sensor on the spacers, the experimental platform of the temperature sensor and spacers model is constructed in this paper. It is studied that the flashover process is acquired with increasing the voltage using the sensor installing on the surface of the spacers, the simulated measuring temperature sensor by the steel, the ultraviolet instrument, and the ICCD. The results show that it is a big effect of the measuring temperature sensors installed on the surface on the spacers.
