| 1 | 双馈式可变速抽水蓄能机组无功特性分析显示文摘分析双馈式可变速抽水蓄能机组的无功输出特性,对于提高机组并网运行能力及电力系统电压稳定性具有重要意义。提出了一种基于V形曲线分析机组定子侧无功特性及调节机理的方法。建立双馈电机等效电路及数学模型,分析不同运行工况下双馈电机各电气量的相量关系,得到定子电流随转子电压变化的V形曲线。研究了不同运行工况下V形曲线变化情况,重点分析了有功功率、转差率对V形曲线变化影响。基于Matlab/Simulink平台分别进行稳态和动态仿真验证,仿真结果表明双馈异步电机具备类似于同步电机的无功调节特性,证明了V形曲线法对于系统无功特性分析结果的正确性和有效性。 | 王欣竹 韩民晓 Bitew Girmaw Teshager | 2019 | 电网技术2019，43，8： | 11 |
| 2 | Wind Power Fluctuation Compensation by Variable Speed Pumped Storage Plants in Grid Integrated System:Frequency Spectrum Analysis显示文摘Electrical power generation from wind technology is the most rapidly growing technology due to its ample characteristics.Nevertheless,because of its stochastic feature,it has the unnecessary impact on the operations and stability of the power grid system.The fluctuation of the grid frequency problem,for example,is more pronounced.The fluctuation of the frequency in turn impacts even the collapse of the power system.To minimize such problems,a droop-vector control strategy applied on a doubly-fed induction machine based(DFIM)variable speed pumped storage(VSPS)system is proposed in this paper.This method is should be used as a wind power fluctuation compensation solution in the wind farm-grid integration system.The system model is made on the basis of the technique called a phasor model.The frequency spectrum analysis approach is used in the VSPS plant for determining the dynamic performances of the grid in case of contingencies including wind power fluctuation compensation.The software platform MATLAB/Simulink is used for verifying the performance of the proposed system.The results show that the method of the frequency spectrum analysis technique is effective for determining the wind power fluctuation and stability requirements in large power networks.The control strategy proposed in this paper implementing the VSC-DFIM based VSPS plant integrated with the power gird and wind farm network achieves a well-controlled power flow and stable grid frequency with the deviations being in acceptable ranges. | Minxiao Han Girmaw Teshager Bitew Sifrash Amogne Mekonnen Wenli Yan | 2021 | CSEE Journal of Power and Energy Systems2021，7，2： | 3 |
