The power supply has the functions of IGBT driver, over-voltage protection, over-current protection, over-heat protection and fault locking.

Dynamic modeling and analysis on cascading failure of complex power grids;

Risk assessment of cascading failure in power system based on fuzzy neural network;

Review of cascading failures in electric power network;

According to complex system theory, power systems in self-organized criticality (SOC) state have high probability of occurring of cascading failures.

With the development of complex network theory,especially the discovery of small-world characteristics in the power grid,increasingly great concern is shown about the relationship between the complex structural characteristic and the cascading failures of power grid.

For the sake of determining the impact of small-world property on probability of occurring cascading failures in power systems, the cascading failures are simulated in several power systems among which some have small-world property and the others have stochastic network property.

It is greatly relevant to serious failures,particular to the cascading outages.

Forecasting and preventing strategy for cascading outages is primarily discussed in this paper according to the rule of successive breaks in cascading outage process of power grid.

Many severe cases of black outs have taken place recently among different countries, most of which exhibit cascading outage, so the study on cascading outage of power grid is becoming more and more popular.
