Research of Black Start Strategy of West Inner Mongolia Power Grid;

With the development of Western Mongolian Power Net (hereinafter referred to as Western Mongolian Net), the formation of the power net becomes more and more complicated.

Directiong against improper jointing point of returned cooling water from slag cooler of 2×300 MW units in Mengxi Power Plant,the decrease of integral cycle efficiency and its influence upon economic efficiency in operation of the units have been analysed,and an optimized improvement scheme being put forward on the basis of data obtained from results of analysis.

Analysis on Jiangxi power grid damage caused by ice disaster and countermeasures;

Countermeasures of scale grid-connected PV power station in Jiangxi power grid

The paper analyzed 220 kV and above transmission line lightning trip-out in Jiangxi power grid from January to July,2009.

In the light of the characters of greater peak-valley difference & higher stability operation demand to power grid,started from Shaanxi power network load,power source current state and planning,peak-valley difference load and frequency & peak capacity regulation are analyzed in detail.
