提出一种基于测试信号法的统一潮流控制器(UPFC)附加阻尼控制器设计方法。首先运用测试信号法进行系统小信号稳定性分析;然后运用测试信号法求得从UPFC有功功率指令值到并联交流联络线有功功率的开环传递函数;最后基于经典控制理论的极点配置算法便可整定UPFC附加阻尼控制器的各个参数。利用PSS/E验证了所设计的UPFC附加阻尼控制器的有效性。以南京西环网系统为例,验证所提出的UPFC附加阻尼控制器设计方法在实际电力系统中应用的有效性。

对某抽水蓄能电站二次系统的接地方案进行研究,结合其站内枢纽布置分散和地理位置特殊等特点,发现其在二次电缆的防护和二次设备柜体的等电位连接方面存在不足。因此提出了对二次电缆屏蔽层在控制处一端接地的基础上,对二次电缆全线穿金属钢管和二次设备柜体的接地铜排在一点接地的基础上,去除接地铜排与室内等电位连接铜网之间相连的绝缘子,并使用短线技术就近接地的多点接地防护方案,进行进一步优化。通过电磁暂态仿真软件ATPEMTP仿真得出,在雷电流干扰下此优化措施既使二次电缆芯线感应电压大大降低,又消除了柜体接地铜排对柜内二次设备造成的反击,验证了优化措施的合理性。

Journal of Oceanology and Limnology 2019年第4期37卷 1372-1381页

作者： LIU song LI Bing CHEN Xiaolin QIN Yukun LI pengcheng CAS Key Laboratory of Experimental Marine Biology Institute of Oceanology Chinese Academy of Sciences Qingdao 266071 China Laboratory for Marine Drugs and Bioproducts Qingdao National Laboratory for Marine Science and Technology Qingdao 266000 China Center for Ocean Mega-Science Chinese Academy of Sciences Qingdao 266000 China Marine Science and Engineering College Qingdao Agriculture University Qingdao 266000 China

In this study, a polysaccharide from Enteromorpha prolifera (EP) was extracted and its effect on maize seedlings under NaCl stress was investigated. Firstly, the components and structure of the EP were determined. We found that EP is a sulfated polysaccharide of high-molecular weight (Mw, 1 840 KDa) heteropolysaccharides and the main monosaccharide is rhamnose. The polysaccharide was applied to explore its effect on the growth of maize seedlings and its defense response under a salt stress. The results show that EP could promote the growth of maize seedlings under the salt stress. In addition, EP was shown able to significantly regulate membrane permeability and adjustment of osmotic substances such as soluble protein, soluble sugar, and proline, antioxidant enzymes containing superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase. Therefore, EP is an effective salt-resistant substance for the growth of maize seedlings under NaCl stress.
