Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.
以励磁故障后发电机端的相关参数的变化为基础,通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析,发现:励磁故障是一个大干扰稳定性问题,励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异,已远非正弦曲线,因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想;异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆,它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆,但不能保证完全失磁之外的其它状态不会进入该阻抗圆,因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。

This model decompounds the cooperative partners of virtual enterprises as the roles of the agile supply through analyzing the business process of the agile supply chain; an agent stands for one role of the agile supply chain. We give the architecture of agent negotiation and the reasoning process model based multi-agent negotiation with fuzzy logic control after analyzing the process of multi-agent negotiation. An evaluating principle of the cooperative partners is given for this reasoning process model firstly, then, we analyze the factor, which affect the agent evaluating the cooperative partners with the principle. An evaluation index system is designed for multi-agent and multi-issue and multi-level negotiation, then, we evaluate the proposal in the agent negotiation with the index system fuzzily and synthetically and the result range from 0 to 1. This evaluation method is generic, furthermore, for the adaptability of agent, partiality of agent can be defined manually or automatically, the user can adjust the partiality with changing the weight to optimize negotiation results.
该模型在分析了敏捷供应链的业务流程的基础上将动态联盟的合作伙伴企业按角色进行分解,用Agent来代表每个角色,在分析了Agent谈判的过程之后给出了谈判Agent的体系结构,然后给出了基于模糊逻辑控制的Agent的谈判推理模型,该推理模型首先建立了合作伙伴企业评价体系的原则,并基于此原则分析了影响Agent对合作伙伴企业的评价因素,然后建立了多Agent多问题多级评价指标体系,并基于该指标体系对Agent在谈判中的建议进行模糊综合评价,评价结果是位于区间[0,1]上的值,该评价方法不仅具有通用性,而且Agent可以通过调整各级指标的权重来定义自己的偏好。

The new rT joint not only has two rotation axes that intersect at right angle,but also has another rotational degree of freedom which can be used to modify the assembly of other joints.This can change the mobility of the parallel mechanisms that assembled with the new rT joints and leads to two types of metamorphic paralllel mechanisms:In the first type,the mechanism changes its topology by turning the new rT joints in all limbs into different configurations which reconfigures the constraints within the limbs or the assembly of all the limb constraints.This change of mobility is completed by two cases.One is illustrated by a 3PS and a 3C parallel mechanism,by altering the rT joint into different configurations there will produce or reduce local degrees of freedom and thus change the constraits to the moving platform.This qualifies the 3PS and 3C to have variable mobility from 3 through to 6 and from 1 through to 6 respectively.
该铰链除了一般Hooke铰的两个轴线互相垂直相交的旋转自由度外,还增加了一个可以调节该两个轴线之一的姿态的一个旋转自由度,通过此自由度调节该rT铰到不同的装配构型,可以改变用其装配的并联机构的自由度,由此产生两类新型的并联变胞机构:一类是机构的各个支链中都有rT铰,该铰链的不同构型可以改变各支链对运动平台的约束或整个支链组的组合形式而改变机构的自由度状态,3PS和3C属于前者,通过调节rT铰到不同构型可以使其支链产生或消失局部自由度,从而减少或增加支链对运动平台的约束,使得并联变胞机构3PS和3C分别具有自由度从3变到6和从1变到6的能力;3P属于改变支链组组合形式的机构,其rT铰的不同构型将改变整个支链组的几何约束组合,使得并联变胞机构3P可以有三转动、三平动或三平移(来源:ABCded9de论文网www.abclunwen.com)一转动的自由度形式。
