【摘要】：通过分析现有变电站内二次系统存在的设计、施工及设备存在的问题,参考实际运行与维护经验,从设计者的角度对工程建设各阶段提出改进建议,确保电网安全运行和可靠供电。引入全寿命周期理念,提出了变电站二次设计模块化设计,以在变电站全寿命周期内减少改造、扩建所对整站运行的影响。分析得出元件、设备的寿命与使用环境息息相关,由设计角度提出改善环境的措施,并对设备设计提出合理建议。基于全寿命周期成本考虑变电站二次设备电子、微机设备更新换代速度快,运用“浴盆曲线”对易损元器件寿命周期分析,提出设计人员在技术协议中签订设备维护服务周期,更明确备品备件在整个工程中的数量。通过提出新的仓储模式,为备品备件长期保存提供更可行方案。
[Abstract]:Based on the analysis of the problems existing in the design, construction and equipment of the secondary system in the existing substation, and referring to the actual operation and maintenance experience, this paper puts forward some suggestions for improvement in each stage of the project construction from the point of view of the designer, so as to ensure the safe operation and reliable power supply of the power grid. The concept of whole life cycle is introduced, and the modular design of substation secondary design is put forward in order to reduce the influence of transformation and expansion on the operation of the whole station during the whole life cycle of substation. It is concluded that the life of the equipment is closely related to the operating environment, and the measures to improve the environment are put forward from the design point of view, and some reasonable suggestions for the design of the equipment are put forward. Based on the whole life cycle cost, considering the secondary equipment electronics of substation and the fast replacement speed of microcomputer equipment, this paper analyzes the life cycle of vulnerable components by using "bath basin curve", and puts forward that the designer signs the equipment maintenance service cycle in the technical agreement, and clarifies the quantity of spare parts in the whole project. By putting forward a new storage mode, it provides a more feasible scheme for the long-term preservation of spare parts.
