本文区别于其他传统的人口预测模型，深入分析了当前中国人口的基本情况，以及 最近几年中国人口的发展情况与趋势，针对中国人口基数大、男女比例不协调、乡村人 口城镇化加速、人口老龄化日益严重等显著特点，在各年龄段生育率短期内保持不变的 假设下，建立基本的人口转移回归模型，用于模拟预测短期内中国各类人口数量发展变 化。该模型预测结果显示，中国人口在未来十几年内增长一定幅度后开始下降；与此同 时，人口老龄化、男女比例失调等问题日益严重。该模型短期内的预测效果比较好。 为了使中国将来的人口发展健康、平衡，综合考虑中国以及欧洲一些发达国家和亚 洲一些实行计划生育较早的国家以前以及当前的一些情况，本文提出了修改计划生育政 策的建议。面对日益严重的老龄化现象，我们提出生育率应该参考老龄人口比例这一新 思想，并建立生育率与老龄人口比例的关系模型，用于长期人口的预测。预测结果显示 中国总人口在短期内持续上升，在2025 年到2040 年之间基本保持在14.6 亿的最大值， 然后开始缓慢下降。 两个模型的结果均显示，中国将会面临严重的老龄化和男女比例不协调两个问题。 最后我们提出了适当措施以缓和这两个问题带来的影响。(This is different from other traditional population projection model, in-depth analysis of the current basic situation of China s population, and In recent years the development of China s population and the trend for China s huge population, gender disharmony, rural people I accelerated urbanization, the growing aging population and other significant features in the short term fertility of all ages remain unchanged Assumption, the establishment of basic population transfer regression model, to simulate and predict the short term development of China s various types of population change Of. The predicted results show that China s population growth in the next decade began to decrease after a certain extent and the same When an aging population, gender imbalance and other growing problem. The model predicted the short-term results were better. To make the development of China s future population health, balance, considering China and some developed countries in Europe and A)

首先介绍了辐射状配电网三相潮流计算方法，对几种常用的配电网潮流计算方法进行了对比分析，着重介绍了配电网潮流计算中常用的前推回代法的基本原理，并利用Matlab仿真软件编写了相应的潮流计算程序，通过33母线系统对计算程序进行了仿真验证。然后介绍了含弱环网的配电网潮流计算的处理方法，编写了相应的仿真计算程序，并通过算例仿真予以验证。接着介绍了分布式电源并网的几种接口模型以及分布式电源在潮流计算中的数学模型，分析了在潮流计算过程中PQ、PV、PI节点的处理方法，特别是对PV节点的处理方法进行了详细的介绍。最后针对不同分布式电源并网的状况分为四种方案进行了仿真测试，验证了本文所编写的潮流计算方法在处理计及分布式电源的配电网三相潮流的正确性。(First introduced the radial distribution network three phase power flow calculation method for several common distribution power flow calculation methods were compared, highlighting distribution power flow calculation of the basic principles of common forward and backward substitution method, and the use of Matlab simulation software written in the corresponding flow calculation program, through the system bus 33 to a simulation calculation program. Then introduces the method of treating a distribution power flow calculation weak ring, write the corresponding simulation program and simulation to be verified by an example. Then interface model introduces several distributed power grid and distributed power flow calculation in mathematical models, analyzes the trends in the calculation process PQ, PV, PI node processing method, especially for PV node approach a detailed description. Finally different distributed power grid situation is divided into four scenarios simulation test to verif)
