Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3, Pages 321-332 doi: 10.1007/s11465-017-0434-1

Abstract:

The magnitude and stability of power output are two key indices of wind turbines.This study investigates the effects of wind shear and tower shadow on power output in terms of powerfluctuation and power loss to estimate the capacity and quality of the power generated by a wind turbinePower fluctuation and power loss due to wind shear and tower shadow are analyzed by performing theoreticalUnder steady wind conditions, power loss can be divided into wind farm loss and rotor loss.

Successful Practice in Management Reform——An Analysis of Experiences with Guangzhou Pumped Storage PowerStation

Luo Shaoji

Strategic Study of CAE 2000, Volume 2, Issue 11, Pages 52-59

Abstract:

The 2 400 MW Guangzhou pumped storage project became fully operational in March 2000, thus establishing itself as the biggest of its kind in the world.

Based upon successful experiences with the project, the author spotlights the management practices in the four parts: that is project management improvements, reforms on construction management, reforms on plant operation management and reforms on business strategy. Thanks to the above-said reform efforts, the project turns out to be quite a success in terms of cost saving, fast progress, good engineering quality, rich returns plus a friendly environment.

Equivalent circuit and characteristic simulation of a brushless electrically excited synchronous windpower generator

Hao WANG, Fengge ZHANG, Tao GUAN, Siyang YU

Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3, Pages 420-426 doi: 10.1007/s11465-017-0439-9

Abstract:

A brushless electrically excited synchronous generator (BEESG) with a hybrid rotor is a novel electrically excited synchronous generator. The BEESG proposed in this paper is composed of a conventional stator with two different sets of windings with different pole numbers, and a hybrid rotor with powerful coupling capacity. The pole number of the rotor is different from those of the stator windings. Thus, an analysis method different from that applied to conventional generators should be applied to the BEESG. In view of this problem, the equivalent circuit and electromagnetic torque expression of the BEESG are derived on the basis of electromagnetic relation of the proposed generator. The generator is simulated and tested experimentally using the established equivalent circuit model. The experimental and simulation data are then analyzed and compared. Results show the validity of the equivalent circuit model.
