摘要
煤电机组作为燃煤电厂的核心设备,由控制保护系统保证机组正常工况下的控制调节和异常工况下的保护动作,随着技术的发展以及电厂机组信息数据入网的要求,控制保护系统遭受网络安全攻击的次数日益频繁,如不及时有效处理往往使得机组处于危险工况进而造成主设备损坏等安全事故发生。因此根据煤电机组危险工况的触发条件,提出危险工况触发边界条件,通过改变控制保护逻辑实现危险工况的触发。本文通过搭建煤电机组半实物仿真平台对煤电机组的3种危险工况进行仿真研究,确认其边界条件,对煤电机组控制保护系统安全防护提供有效参考。
As the core equipment of a coal-fired power plant,the control and protection system of the motor unit ensures the control and adjustment of the unit under normal working conditions and the protection action under abnormal working conditions.The number of network security attacks is becoming more and more frequent.If it is not dealt with in a timely and effective manner,it will often put the unit in a dangerous working condition and cause safety accidents such as damage to the main equipment.Therefore,according to the triggering conditions of the dangerous working conditions of coal-fired power units,the triggering boundary conditions of dangerous working conditions are proposed,and the triggering of dangerous working conditions can be realized by changing the control protection logic.In this paper,by building a semi-physical simulation platform for coal-fired power units,the simulation research of three dangerous working conditions of coal-fired power units is carried out,and the boundary conditions are confirmed to provide an effective reference for the safety protection of the control and protection system of coal-fired power units.
