This paper presents a new time-varying power system short-term load model based on the α stable distribution that can satisfactorily simulate the features of the high capacity impact load.

Stabilized current measures of rectification units co-net with impact load;

The impact loads of grand steel plant have influence on the stability of power system, especially the transient stability of the regional power system with weak power grid structure.

Using the anaerobic baffled reactor(ABR) to treat the domestic wastewater,this paper researched on the influence of each room of ABR when organic shock loading and hydraulicshock loading are changing.

The effect of shock load on performance of the reactor was studied.

The a bility to resist shock loading could be enhanced by supplement of trace metals t o the anaerobic reactor.

The microbial community structure in the bioaugmented system for refinery wastewater treatment and the changes in this system when it received shock loading were studied using ERIC-PCR technology.

In this study, conventional activated sludge (CAS) systems, which were generally used to treat municipal wastewater, were modeled to receive intermittent 2,4-dichlorophenol (2,4-DCP) shock loadings.

Intermittent and continuous shock loading had been observed during the 5-month operation of sorbitol wastewater treatment system using activated sludge process.
