| 7. | In actual system , using expert system every vca is more reasonable in engineering . when we ' ll carry out voltage rectification , we consider that different control variables have different sensitivity . so the action of control facilities should be more reasonable
在实际系统中，从工程应用的角度利用专家系统使分区的结果更加合理，并且在电压校正的时候考虑了不同控制变量的灵敏度不同，使得控制动作更加合理。 |
| 8. | The secure interactions between enterprises involves with trust relations between different pki domains . for the individual characterizations of a virtual enterprise , on the idea of virtual ca ( vca ) , this dissertation analyzes the practical cases of virtual enterprises and brings forward a new solution scheme which is more secure and more practical
企业的支全交互涉及不同pki域的信任关系，由于商务电于化下的虚拟企业有其自身的特殊性，论文根据虚拟ca （ vca ）的思想，在分析了实际案例的基础上，提出了新的更安全和更符合实际的解决方案。 |
| 9. | Accordingly , using graph theory and operating experience abroad for reference , it firstly brings forward a new method of voltage rectification which based on pilot bus with voltage control area in view of the weak coupling among every vca ( voltage control area ) , using decomposing method of multi critical value , it realizes the eliminating vinculum of every vca . and then , the rectification starts by pilot bus voltage of every vca . so the resolution of whole power net is diverted into calculating smaller sub - net
由于各个电压控制区之间无功电压的弱耦合性，利用多阀值分解的分区算法，实现区域间的解耦，然后根据各个子网络的主导节点的电压进行校正，从而把求解整个网络的问题转化为求解各个小的子网络，降低了网络维数，减少了无功设备控制动作次数，提高了校正成功率，缩短了计算时间。 |
