说明： 所谓下垂控制就是选择与传统发电机相似的频率一次下垂特性曲线（Droop Character）作为微源的控制方式，即分别通过P/f下垂控制和Q/V下垂控制来获取稳定的频率和电压，这种控制方法对微网中的微源输出的有功功率和无功功率分别进行控制，无需机组间的通信协调，实现了微源即插即用和对等控制的目标，保证了孤岛下微电网内电力平衡和频率的统一，具有简单可靠的特点。(The so-called droop control is to select the frequency droop characteristic curve similar to the traditional generator Character) as the control mode of micro source, i.e. to obtain stable frequency and voltage through P / F droop control and Q / V droop control respectively, this control method controls the active power and reactive power of micro source output in micro network respectively, without communication coordination between units, realizes the goal of micro source plug and play and peer-to-peer control, and ensures the power level in micro grid under island The unity of balance and frequency is simple and reliable.)

加强肋
理想的设计
为了克服壁厚大可能引起的问题，使用是一种可减少壁厚并能增加刚性的有效方法。
一般来说，部件的刚性可用以下方法增强
增加壁厚；
增大弹性模量（如加大增强纤维的含量）；
设计中考虑。
如果设计用的材料不能满足所需刚性，则应选择具有更大弹性模量的材料。简单的方法是增加塑料中增强纤维的含量。但是，在特定壁厚下，这种方法仅能使刚性呈线性增长。更有效的方法是使用经过优化设计的。由于惯性力矩增大，部件的刚性便会增大。在优化的尺寸时，不但要考虑工程设计应当考虑的问题，还应考虑与生产和外观有关的技术问题。
优化的尺寸
大的惯性力矩可很容易地通过设置又厚又高的来实现。但是对热塑性工程塑料，这种方法常会产生制品表面凹痕、内部空洞和翘曲等问题。而且，如果的高度过高，在负荷下结构将有可能膨胀。出于这种考虑，必须在合理比例内保持的尺寸（见图1）。-stiffened ideal for the design of large thickness overcome the problems that may arise. use of a reduced wall thickness and rigidity can increase the effective method. In general, the rigid parts of the following methods can be used to enhance increased thickness; increased elastic modulus (such as increasing fiber content); Design considerations. If the design of the materials used can not meet the rigid requirements, they should have a greater choice of elastic modulus of the material. The simple way out is to increase plastics reinforced fiber content. However, in s
