摘要

针对基于在线监测装置的输电线路安全评价的准确性、成本和可靠性等问题，提出通过校核部件运行应力与实际强度的线路本体结构安全评价新方法。应用还原论和反演论思想，构建复杂工况条件下多模态线路力学模型，推导相应部件应力求解方法;考虑部件长期运行强度影响因素及评判专家知识的不确定性，建立了强度模糊综合评价模型。基于J2EE的SSH（Swing，Spring，Hibernate）三层架构，设计并开发相应的安全评价系统。应用实例证明了系统的有效性和可靠性，评价结果可为电网安全措施与预控调度提供科学决策依据。

Abstract

Based on the veracity，cost，and reliability problems of the on-line monitoring device for the transmission line safety evaluation，a novel method of the line ontology structure safety evaluation is proposed，which works by checking the operating stress of the components and their actual strength.By applying reductionism and inversion theories，a multimode line mechanical model is developed under complex conditions，and the calculating formula of the stress for the corresponding components is derived.By taking the influencing factors of long-term operation and the uncertainty of the experts' knowledge of the evaluations into consideration，a fuzzy comprehensive evaluation model is built.On the basis of the J2EE struts-spring-hibernate（SSH）three-tier architecture，the corresponding software system is designed and realized.Examples are given to prove the validity and reliability of the system.The results provide the scientific decision basis to the power-grid for safety measures and pre-control.
