In recent years safety accidents of large-scale wind turbine occur frequently. Because of the structure specialization of wind turbine, in case of an accident, the entire unit is often completely destroyed and economic losses will be very high. This paper presents some phased research results on serious wind turbine accidents and put forward appropriate countermeasures for different types of accidents.

In China, wind power industry has undergone great development in the last few years, while several cascading faults happened in 2011, reveal that terminal voltage of wind turbine generator (WTG) should be monitored and controlled. Furthermore WTGs and static var compensators/generators (SVC/SVGs) need to be coordinated to provide voltage service for the whole network. In this paper, a network model based coordinated automatic voltage control (AVC) strategy for wind farm (WF) is proposed: three control modes out of eight control zones are defined and implemented to accomplish three control objectives. A test AVC system is built to prove the proposed characteristics, and on-site applications in WFs are ongoing now.

This paper presents a novel model of a circuit breaker coil based on electromechanical energy conversion principles which can be employed in circuit breaker condition monitoring. The proposed model takes into account the following: the coil core, springs, magnetic arm and coil. Based on this model, different parameters such as: Friction, the circuit breaker control circuit, inductance of the core and tolerances of the components can affect on coil current are considered.

A comprehensive framework for probabilistic vulnerability assessment based on two level system model is presented. The impact of both internal and external factors on power system is incorporated in this method. The probability distribution of vulnerability is used as the measure of system vulnerability. An effective method to implement the model in multi-machine power systems is developed and an illustrative example is given. The result shows that the method can give system vulnerability level in real time, evaluate the effect of system control, and assess the sensitivity to the external interference.

The micro-grid technology that integrates distributed generations, energy storage element and loads is an effective approach to solve the interconnection of large-scale distributed generations with power grid. Wind and solar can be complementary to each other in time, therefore wind and PV hybrid power system could make full use of clean energy and have high reliability. Smooth switching between grid-connected mode and islanding mode is important to micro-grid stable operation. In this paper a micro-grid model based on wind and PV hybrid power system is built with DigSILENT/PowerFactory. The improved control strategy of P-Q control and droop control combination is proposed and the transition state simulation as to the micro-grid mode switching process is carried out. The result shows that this advanced control strategy can ensure power balance and reasonable power assignment, it also could keep connected bus voltage and micro-grid frequency stable during micro-grid mode switching.

Nowadays distribution system operators are equipped with many real time operation data from SCADA, intelligent electronics devices (IED), automatic meter reading (AMR) and advanced metering infrastructure (AMI) systems. Customer and transformer loading data obtained from AMI system at different time intervals give an opportunity to develop a distribution state estimation (DSE) algorithm. DSE is enabler of many smart distribution applications. In this paper, a DSE based quasi real time search for potential irregularity of electricity usage is presented. The proposed approach can be used to reduce non-technical loss in the distribution network.

The combination of space vector and one-cycle control method could make the controller structure much simple in three-phase three-wire active power filter (APF) with one-cycle control method. But in traditional methods, 6 sextants are divided at a frequency cycle in the whole range of space vector area. In this paper, the whole 6 sextants are divided in a novel method and section 1&2, section 3&4, section 5&6 can be merged respectively, and so only 3 sextants are required for the realization of space vector. As a result, the implementation of the controller is much simple. Simulation results show that the proposed method has a good compensation effect and validate the method is feasible and effective.
