启动方案智能编制系统技术研究

随着智能电网的不断建设,在电力调度领域中,设备启动方案的编写与校验也应与时俱进。通过人工方式编写启动和校验方案,不仅无法快速完成任务,还易产生遗漏,降低工作效率和方案可靠性。电网设备启动方案智能编制系统(Intelligent Start Programming System for Grid Equipment)以电力系统各项安全操作规程为实际操作纲领,以五防锁为操作防护措施,可保证现场人员电力试验时操作安全进行。本系统涵盖启动方案规则库、启动方案智能生成模块及系统联动机制,采纳多项数据作为参量,以电网调度大数据进行方案预判,提高启动方案的合理性和可靠性。该系统可在Linux和Windows系统上运行,可快速出具启动方案、易出危险操作过程及应急处理方案,具有较强的兼容性和实用性。

新设备入网启动标准化管理

通过分析近年新设备启动投运经验和入网启动批准书执行情况,梳理和发现了新设备启动管理和技术层面的问题及隐患,倡导新设备启动实施"计划"管理,列入电网月度检修计划工作范畴,实施"电网大检修计划"管理理念,制定新设备启动计划管理标准化流程;在启动方案前期准备工作中,引入"感性经验"与"定量精准计算"相结合的启动方案编制管理模式,从制度层面保障新设备安全入网,制定"新设备入网启动批准书"标准化模板,实行入网批准书回执流程,实施闭环管理,保障新设备启动的安全稳定经济运行。

Intelligent manufacturing system of impeller for computer numerical control(CNC) programming based on KBE

To solve the problem of advanced digital manufacturing technology in the practical application, a knowledge engineering technology was introduced into the computer numerical control(CNC) programming. The knowledge acquisition, knowledge representation and reasoning used in CNC programming were researched. The CNC programming system functional architecture of impeller parts based on knowledge based engineering(KBE) was constructed. The structural model of the general knowledge-based system(KBS) was also constructed. The KBS of CNC programming system was established through synthesizing database technology and knowledge base theory. And in the context of corporate needs, based on the knowledge-driven manufacturing platform(i.e. UG CAD/CAM), VC++6.0 and UG/Open, the KBS and UG CAD/CAM were integrated seamlessly and the intelligent CNC programming KBE system for the impeller parts was developed by integrating KBE and UG CAD/CAM system. A method to establish standard process templates was proposed, so as to develop the intelligent CNC programming system in which CNC machining process and process parameters were standardized by using this KBE system. For the impeller parts processing, the method applied in the development of the prototype system is proven to be viable, feasible and practical.
