Asian Agricultural Research 2015年第10期7卷 63-66 70页

作者： Yuji JIN meina jiang Agricultural College of Yanbian University

with expansion of rural empty nesters,endowment of empty nesters has become a hot spot of the society. By means of questionnaire survey and interview,this paper analyzed basic situations of empty nesters in Tulu Village of Hunchun City in Jilin Province,including economic level,physical health,life care,and spirit situations. Next,it discussed major problems in endowment problem of empty nesters,including limited economic support,unoptimistic physical health,low ability of life care,and feeling of loneliness. Finally,it came up with pertinent recommendations on the basis of the analysis,including strengthening family endowment ability and improving socialized endowment service,strengthening practical living ability,improving life care ability with family endowment as primary and community endowment as auxiliary part,and expanding amusement and recreation ways of empty nesters.

考虑到实现和控制的经济实用性,针对低压配电网中静止无功发生器(SVG)的运行控制问题,提出了一种改进式控制策略,该控制策略有恒无功、恒电压两种控制方式,能满足不同用户、不同地区的功率补偿需求。其中,恒无功模式下的外环控制通过简单计算直接解耦q轴电流,避免了比例积分(PI)调节。通过在PSCAD/EMTDC中搭建的SVG系统仿真模型,对所提出的控制策略进行了仿真验证,并提供了大量的实验和仿真数据,仿真结果表明:依据该控制策略设计的SVG系统响应速度快,直流电压稳定性好,动态补偿性能优,同时实现简单,因而具有一定的实用推广价值。
