Description

地下变电站辅助系统的计算机监控方法
技术领域
本发明涉及一种辅助系统的计算机监控方法,尤其是涉及一种地下变电站辅助系统的计算机监控方法。
背景技术
目前,大型地下变电站的辅助工业系统主要包括各工艺设备间和电缆层等的通风、制冷系统、变电站的火灾报警系统、设备冷却水的处理和循环冷却系统、供排水系统等,上述辅助工业系统有的是保障地下变电站的主体电气工艺系统和设备运行必不可少的部分,如变压器、电抗器等的循环冷却水系统及其补充水的处理系统;有的是为防止和减少火灾、渗水等对变电站的危害,保护设备和人员安全的重要设施,如火灾报警系统、排水系统等;制冷通风系统等则是保障变电站工艺设备长期安全和稳定运行及提供检修和运行人员一个适宜的工作环境所必需的辅助系统。随着近几年控制设备和通信网络等技术的进步,也为辅助工业系统的监控达到更高的自动化水平和安全可靠性提供了可能,但现有技术中没有能将各系统有效综合监控的系统,从而为管理维护地下变电站增加了工作量与难度。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种地下变电站辅助系统的计算机监控方法。
本发明的目的可以通过以下技术方案来实现:地下变电站辅助系统的计算机监控方法,包括以下步骤:1)采用同一控制器同时控制变电站内的主变和电抗器循环冷却水系统、超滤和反渗透系统、暖通空调系统和给排水系统;2)采用冗余通信措施保证可靠性的条件下,在同类工艺系统的控制中全部采用布置在被控对象附近的远程I/O站;3)通过系统可靠性分析计算和性价比论证,确定采用系统可靠性更高的大型PLC作为系统的主控设备。
与现有技术相比,本发明使系统简洁可靠,消除了各控制系统最终联网所需的通信接口,减少控制系统设备的配置数量、编程组态统一,减少电子设备室/继保室的面积,减少控制电缆长度,较I/O机柜集中布置在电子设备室/继保室的传统方案可节约电缆超过1/4,同时相应减少因电缆感应的电磁干扰,采用大型PLC控制器较采用多套小型PLC将使整套控制系统具有更高的系统可靠性。
具体实施方式
地下变电站辅助系统的计算机监控方法,包括以下步骤:1)采用同一控制器同时控制变电站内的主变和电抗器循环冷却水系统、超滤和反渗透系统、暖通空调系统和给排水系统;2)采用冗余通信措施保证可靠性的条件下,在同类工艺系统的控制中全部采用布置在被控对象附近的远程I/O站;3)通过系统可靠性分析计算和性价比论证,确定采用系统可靠性更高的大型PLC作为系统的主控设备。
采用同一控制器同时控制变电站内的主变和电抗器循环冷却水系统、超滤和反渗透系统、暖通空调系统和给排水系统等有着各不相同监控要求的工艺系统,在采用冗余通信措施保证可靠性的条件下,首次在同类工艺系统的控制中全部采用布置在被控对象附近的远程I/O站,既减少了继保室的面积,也节约了1/4以上的电缆同时减少了由电缆引入的电磁干扰,通过系统可靠性分析计算和性价比论证,确定采用系统可靠性更高的大型PLC作为系统的主控设备,根据对实际条件的分析,其监控系统的配置与以往常规的控制方案在主要控制设备的选择、控制系统的划分及控制系统的配置和布置等均有非常大的改进,本发明提出的控制系统方案模式更加符合大型地下变电站辅助工业系统的配置和布置特点,便于实施和运行监控及维护。所采用的方案充分利用了当前PLC产品的多任务处理功能、先进的网络接口能力和冗余能力等,最大程度上提高了系统的可靠性。
