作者： B. T. Li Y. L. Li Key laboratory of power system simulation and control of ministry of education Tianjin University TJU Tianjin China

Intelligent control technology of tripping and reclosing is present for double-circuit transmission line on the same tower aiming at solving the problems existing in reclosure commonly used nowadays. Way of only tripping faulty conductor(s), which can enhance the power transmission on condition of fault, is applied for each fault type. Identification of transient and permanent fault based on fault point voltage is carried out after tripping. If permanent fault occurs, the whole fault circuit(s) is(are) opened and reclosure(s) is(are) locked; if transient fault occurs, reclosing scheme in phase order is started. Breaker of the remote terminal operates first when reclosing each phase; each reclosing time delay is set at the optical reclosing time in order to damp out the oscillation and stabilize the system; reclosing angle is set at the ideal angle for decreasing transient aperiodic component of the second short circuit current.

IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)

作者： Fengzhang Luo Key Laboratory of Power System Simulation and Control of Ministry of Education Tianjin University TJU Tianjin China

An economic analysis method is proposed for distribution system planning considering the N-1 guidelines, in which the fundamental properties of power supply capability and the economic benefit are combined. The economic efficiency and the potential power supply benefit of a distribution system are thus evaluated. A complete system of economic evaluation indices is presented, including the static profitability indices and the dynamic investment benefit indices. Applications show that this method and index system can take into account both the basic characteristics of distribution system and the special features of power energy that differ from general merchandise. So they can not only evaluate the economic benefits for project investment combining with the traditional approaches of engineering economics, but can also assess the economic benefits of system-owned assets for power supplying effectively, as well as for the economy evaluation of the distribution system in operation or the planning schemes. This method can even be applied to assess the economic benefits of transmission system.

Photovoltaic（PV）generation is the technique which uses photovoltaic cell to convert solar energy to electric energy. Nowadays,PV generation is developing increasingly fast as a renewable energy source. However,the disadvantage is that PV generation is intermittent for depending on weather conditions. Thus,the battery energy storage is necessary to help get a stable and reliable output from PV generation system for loads and improve both steady and dynamic behaviors of the whole generation system. The paper presents detailed transient models of the grid-connected PV/Battery hybrid generation system,and all these models are simulated by using MATLAB/Simulink. PV array is firstly connected to the common dc bus by a boost converter,where the battery is also connected by a bi-directional DC/DCconverter,and then integrated into the ac utility grid by a common DC/AC inverter. Maximum power point tracking helps PV array to generate the maximum power to the grid,and the battery energy storage can be charged and discharge to balance the power between PV generation and utility grid. Finally,different cases are imulated,and the results have verified the validity of models and control schemes.

A novel method, which utilizes harmonic for excitation, is presented to adjust the air-gap magnetic field for permanent magnet synchronous machine. The structure and basic principles of the hybrid excitation PM synchronous generator(HEPMSG) are introduced. The no-load and on-load electromagnetic field are calculated based on finite element method, and the waveform and effective value of the winding voltage and characteristics of the machine are gained for different loads. Calculation results demonstrate the new hybrid excitation scheme is feasible. This new method combines the advantages of PM machines and electrical excitation machines. The machine removes the brushes and slip rings, which makes permanent magnet machine keep simple and highly reliable.

作者： Chao Liu Dongxiang Jiang Jie Chen State Key Laboratory of Control and Simulation of Power System and Generation Equipments Department of Thermal Engineering Tsinghua University Beijing China

A wind turbine rotor system containing blades has its own characteristics. The vibration characteristics of blades with special airfoil can influence the vibration characteristics of the rotor system. This paper analyzed the vibration characteristics of a wind turbine rotor including blades with two-dimensional airfoil. The Finite Element Method (FEM) is applied to establish the rotor model, with the purpose that the FEM can adjust complex blades airfoils and acquire the details of the blades vibration characteristics. The modal characteristics are extracted based on the wind turbine model established in the laboratory. Using harmonic analysis of FEM, the excitation forces on the blades caused by the stochastic wind load are imposed on the rotor model and the stable response of the rotor system is calculated using ANSYS. Then the vibration characteristics are analyzed and the characteristics of the harmonic response are studied under different phases of the circumferential and axial forces.

As an important component of a wind turbine drive chain, the high failure rate of the gearbox can have a serious impact on the operation of wind turbine units. The fault diagnosis of the gearbox is therefore important for the safety of wind turbine units. In this paper, a gearbox experiment rig was built, experiments on the gear surface spalling fault were held on the rig under laboratory conditions, the shaft vibration displacement signals were collected, related vibration signals were analyzed by time domain, amplitude domain, frequency domain and wavelet analysis, and the results of different analysis methods were compared. The results show that the waveform of normal and fault signals are similar, the amplitude of the signals will change while the fault happens, and the wavelet analysis is more effective than frequency domain analysis on gearbox fault features extraction.

Photovoltaic application of LED lighting has been a hot trend in residential illumination, for it integrates the advantages of both the PV systems and LED lights. However, it has a series of problems, such as high thermal loss, poor reliability, and a short life span. To address these problems, this paper presents a deep research on the whole system from a low-cost, high-efficiency and long-life point of view. A main circuit integrating maximum power point tracing (MPPT) control and battery management, as well as a double-loop control for LED load is developed. A set of protection system is applied to ensure high reliability of the system. The control strategies are tested on the demonstrator and prove to be effective.

Now microgrid has aroused increasing attention due to energy sustainable development and the development of distributed generations (DG), such as micro-turbines, gas turbines, wind power, photovoltaic and fuel cells. This paper introduces the basic structure of microgrid and summarizes the overvoltages that can occur in microgrid, including ground fault overvoltages, resonant overvoltages, overvoltage related to voltage regulation, switching overvoltages of inner microgrid, transfer overvoltages from distribution network (such as lightning and switching overvoltages). By analysis, this paper obtains the following conclusion: resonant overvoltages and lightning stroke transfer overvoltages are the most serious for microgrid.

The discrete control technology for AC machine drives is widely applied in the industrial field. This paper aims to excavate new approaches to enhance the discrete control system in AC motor drive systems from following aspects: matching design for discrete subsystems, synchronization in the signal processing and dealing with the restrictions in the voltage output. The proposed approaches are incorporated with three key techniques applied in high performance induction motor drive systems: DC pre-excitation, parameter identification and flux observer with a sensorless control to verify the feasibility. The anti-interference and synchronization procedure in the implementation are also proposed. The experimental results from the test on 55kW/400V and 160kW/400V ASD (Adjustable Speed Drives) systems validate the effectiveness of the proposed approaches.

Due to the current restriction of semiconductor devices, the start-up is an extremely important process in the ASD (adjustable speed drive) system. DC pre-excitation is one of the effective solutions for increasing the starting torque and depressing the starting inrush current. However the effect of DC pre-excitation would be discounted if it could not be compatible with the induction motor drive control system. Also the stability of the DC pre-excitation application is related to its operational mode. This paper addresses the principle of DC pre-excitation and excavates its relationship with current control. The method to improve the stability of DC pre-excitation effectively shielding EMI is detailed. The relevant study has been implemented in a control system for a 55 kW and 160 kW induction motor and the simulation and experimental results validate the effectiveness of the proposed design method.
