Low frequency oscillation (LFO) is harmful to power system security and stability. The traditional solutions for LFO are the power system stabilizers (PSSs) with local signals implemented on the excitations. This paper explores the governor-side damping controllers for LFO with wide area measurement system (WAMS). Design strategy of governor-side damping controller using remote signals from WAMS with time delay is proposed based on the partial state feedback theory, the time delay is dealt with the Pade approximation. Simulation results in a 2-area 4-generator power system show the effectiveness of the proposed governor-side damping controller.

With rapid development of wind power generation, large capacity wind farms are connected into the transmission system. Comparing with traditional power plant, the transient characteristics of transmission grid including wind farm are worthy investigating. The wind farm based-on wound rotor induction generators (WRIGs) shares high market occupancy in China, but academic researches on this grid-connected wind generation are few. So in this paper, the transient characteristics of the power system, adding a WRIGs wind farm and adding a traditional power plant, are compared. Effect of a WRIGs wind farm on transient performances of transmission grid is discussed. And the control effect on transient stability, when the WRIGs wind farm participating in system control during system fault, is investigated. Finally, simulation results are validated by using CIGREB4-39 grid. It is concluded that the transient performance of WRIGs wind farm is better than that of traditional power plant. © 2009 IEEE.

Along with the enhancement of voltage level, harmful affect of the secondary arc current to the system becomes more and more serious. The transmission power of the lines is one of factors that influence the secondary arc current obviously. The voltage distribution along the transmission line will changes according to the different transmission power, which will lead to the variation of the induction component from the sound phases when the fault occurs. In this paper, the quadric-mode transformation is adopted to establish the mathematic model of secondary arc current in the double-circuit transmission line. According to the variation of power transmission, the secondary arc current of different fault point is calculated. The results indicate that secondary arc current is influenced much by the line transmission power, and the variation trend changes along with the fault point. When the fault occurs in head or terminal of the line, the secondary arc current may becomes larger along with the increasing of the transmission power, thus effective suppress measurements must be taken. © 2009 IEEE.

A general problem in the double PWM converter is the voltage unbalance of the dc-link capacitors. This unbalance distorts the waveforms of the output voltage and current. Furthermore, it will lead to instability of the inverter system. Based on the analysis for the unbalance problem, a novel feedback control strategy of DC capacitor voltage deviation is proposed in this paper. The method does not add extra circuit. Build an simulation model of AC-DC-AC converter, the results show that control strategy is correct. © 2009 IEEE.

With the development of electricity demand side market, large consumers have more electricity purchase choices, in the same time have to face the risk of electricity price fluctuation on different markets. In order to measure and hedge the risk reasonably, this paper introduces information entropy as the measure to risk in electricity purchase, by aid of fuzzy optimization, linear membership function is adopted and the optimal electricity purchasing portfolio model is established according to the given expected target and tolerance. Test results show that information entropy can overcome lots of shortages in the method that adopts variance as risk measure;the electricity purchase strategy given by fuzzy optimization has good consideration both on price and risk. ©2009 IEEE.

Along with consuming of fossil energy step by step, crisis of energy has been appeared. The solar energy, which is endless, is a kind of renewable energy. Radiation of sun coming to earth in a day is equal to the energy, which is released by trillion buckets of oil. The research of solar energy generation has stepped into a very activity period. This paper analyses the physics characteristic of photovoltaic array firstly, then researches the mathematical model applying in engineering, and designs the total simulation model based on power electronic circuit in the end. In order to validate the correctness and validity, this paper makes a simulation as an example. The scheme can express the V-I characteristic of photovoltaic array very well. © 2009 IEEE.

In wide area backup protection of electric power systems, the prerequisite of protection device's accurate, fast and reliable performance is its corresponding fault type and fault location can be discriminated quickly and defined exactly. In our researches, global information has been introduced into the backup protection system. By analyzing and computing real-time PMU measurements, basing on cluster analysis theory, we are using mainly hierarchical cluster analysis technology to seek after for the statistical laws of electrical quantities' marked changes. Then we carry out fast and exact identification of faulty components and faulty sections, and finally accomplish fault isolation. Multivariate statistical analysis theory is an efficient theory that can resolve different kinds of complex problems. It has been applied successfully in many researches of various fields, such as geology, weather, hydrology, iatrology, industry, agriculture, and economy, etc. In the study of electric power systems, multivariate statistical analysis theory must also have a good prospect of application. © 2009 IEEE.

Recent years, technologies for new energy have developed rapidly since the energy crisis and the environmental pollution got worse. And the solar energy generation technology tends towards the stage of a large number of applications in engineering from the research stage. This paper designed a grid-connected PV system firstly, then introduced the operation principle of the various parts as well with the control strategy of the power flow. The design of energy storage is of great significance as the output power of PV cells array is greatly affected by the light intensity and the temperature change. Battery is used as the energy storage device normally in the traditional energy storage system. In this paper, it used the Ultracapacitor as the energy storage device after comparing with the battery, and designed the charge-discharge control strategy according to the characteristics of the Ultracapacitor. Finally it verified the feasibility of the energy storage control strategy through the simulation models which was built based on the PSCAD/EMTDC platform. © 2009 IEEE.

On the base of generalizing previously research findings, the authors of the paper apply theory of instant reactive power and theory of unbalanced compensation in the controlling of static reactive-power compensation equipments which can increase power factor and compensate three unbalance, thus simplify the algorithm of the instant reactive power. The formulary of compensating reactance is deduced in the condition of unbalanced load. The model of SVC which may compensate unbalanced load is established with PSCAD. The simulation proves availability and feasibility of the method. In view of the aberrance of bus current in the simulation, the paper analysis harmonic content of three-phase. It is also approved feasible of the algorithm in the condition of seriously disturbing by harmonic. © 2009 IEEE.

Passive islanding detection method is an important concern for grid connected photovoltaic (PV) power generation system due to personnel and equipment safety. Over/Under Voltage protection (OVP/UVP) and Over/Under Frequency protection (OFP/UFP) are basical inverter resident passive islanding detection method (IDM) for detecting an islanding condition by monitor parameters in Point of Common Coupling (PCC) such as voltage amplitude and frequency and then cause the inverter to shut down when there is sufficient transition from normal specified conditions. The real and reactive power equations and Non-Detection Zone (NDZ) of OVP/UVP and OFP/UFP methods for grid connected PV system are derived and analyzed in this paper. Analyses show that the behavior of the system at the time of disconnection will depend on the imbalance power at the instant before the switch opens to form the island, these results also indicate the NDZ of OVP/UVP and OFP/UFP methods is considerable large and the reaction times for these protective methodologies may be variable or unpredictable. © 2009 IEEE.
