具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例提供了一种变电站母线负荷转移方法,请参考图1,其示出了本发明实施例提供的一种变电站母线负荷转移方法的一种流程图,可以包括以下步骤:
步骤101:获取配电网线路的负荷转移编制预案。
其中,负荷转移编制预案包括合环预案和解环预案。
需要说明的是,本发明实施例中的负荷转移编制预案是相对于多条负荷转移线路而言的,即在执行负荷转移编制预案时,便直接实现了多条负荷转移线路的同步转移。
步骤102:判断负荷转移编制预案是否满足第一预设条件。
负荷转移编制预案在执行时必须满足第一预设条件,否则直接认为负荷转移编制预案执行失败,则继续重新编制新的负荷转移编制预案。即在本发明实施例中,通过先校验后执行的要求先对负荷转移编制预案进行校验,当满足第一预设条件时,才能继续执行该负荷转移编制预案。
步骤103:当变电站母线需要转移,且当负荷转移编制预案满足第一预设条件时,执行合环预案,以对相应合环区域的线路进行环网运行;当合环预案执行成功后,执行解环预案,以对相应解环区域的线路进行解环运行。
其中,负荷转移编制预案在满足第一预设条件后,执行负荷转移编制预案,由于负荷转移编制预案中包括合环预案和解环预案,且待负荷转移线路是依照顺序进行合环和解环操作的,故需要先执行合环预案再执行解 环预案。
本发明提供了一种变电站母线负荷转移方法,首先通过获取配电网线路的负荷转移编制预案,并判断负荷转移编制预案是否满足第一预设条件,当变电站母线需要转移,且当负荷转移编制预案满足第一预设条件时,执行合环预案,以对相应合环区域的线路进行环网运行;当合环预案执行成功后,执行解环预案,以对相应解环区域的线路进行解环运行。与现有技术中逐点逐线按顺序实现变电站母线负荷转移的方法相比,本发明提供的一种变电站母线负荷转移方法,不仅缩短了负荷转移时间,还减轻了调度人员的工作量。
请参考图2,其示出了本发明实施例提供的一种变电站母线负荷转移方法的另一种流程图,可以包括以下步骤:
步骤201:获取配电网线路的负荷转移编制预案。
其中,负荷转移编制预案包括合环预案和解环预案。
在本发明实施例中,可以通过以下方式获取负荷转移编制预案,其具体可以为:
分别获取配电网模型及配电网运行方式;依据配电网模型及配电网运行方式获取配电网线路的预案,并将所有预案进行组合,以获取负荷转移编制预案。
需要说明的是,配电网模型及配电网运行方式的获取是依据配电网SCADA系统(Supervisory Control And Data Acquisition,数据采集与监视控制系统)获得的。其中,配电网模型包括配电网开关、配电网馈线段和配电网负荷。配电网运行方式指配电网开关的分合状态。
本发明实施例通过依据配电网SCADA系统自动获取配电网的模型及配电网运行方式,并根据配电网的模型及配电网运行方式通过拓扑搜索获取配电网线路的负荷转移的预案,然后通过组合形成负荷转移编制预案,即本发明中负荷转移编制预案的获取是通过配电网SCADA系统自动形成的,与现有技术中通过人工定制负荷转移编制预案的方式相比,有效的减轻了调度人员的工作量。
需要说明的是,负荷转移编制预案包括合环(控合)和解环(控分), 即控合配电网中的线路联络开关,使配电网线路环网运行,控分变电站出线断路器,使配电网线路解环运行,其中,图3中示出了本发明实施例中提供的依据段塘变电站10kV配电网母线线路的一种变电站负荷转移编制预案的示意图。
步骤202:判断负荷转移编制预案是否满足第一预设条件。
步骤203:当变电站母线需要转移,且当负荷转移编制预案满足第一预设条件时,执行合环预案,以对相应合环区域的线路进行环网运行;当合环预案执行成功后,执行解环预案,以对相应解环区域的线路进行解环运行。
需要说明的是,本发明实施例提供的负荷转移编制预案是基于多条线路预案执行的并集,且多条线路之间是并发执行,互不影响的。在基于多条母线负荷转移线路同时进行转移的基础上,多条母线负荷转移线路中的单条线路的负荷转移编制预案执行过程如图4所示。
当单条线路具有多条预案时,则先排除已经执行失败的预案,再按照负荷转移编制预案的优先级选择待执行的负荷转移编制预案。当单条线路内所有的负荷转移编制预案均执行失败或者当前的单条线路不存在负荷转移编制预案时,则变电站母线负荷转移系统将根据配电网当前运行方式自动生成临时负荷转移编制预案。
其中,对于单条线路的负荷转移编制预案的执行是依据负荷转移编制预案的优先级来实现的,其执行顺序的选择原则如下:
阈值=配电网开关*100+转供后负荷率;
需要说明的是,当阈值越大,则负荷转移编制预案优先级越低,故一般根据阈值的大小来确定负荷转移编制预案的处理顺序。
其中,转供后负荷率可以根据配电网中的历史数据进行估算获得的。
当确定待执行的负荷转移编制预案后,判断负荷转移编制预案是否满足第一预设条件;
当负荷转移编制预案满足第一预设条件时,则控合配电网线路中的线路联络开关,若控合线路联络开关失败,则表明该负荷转移编制预案执行失败,则返回重新选择可以执行的负荷转移编制预案,当控合线路联络开关成功后,则控分变电站出线断路器,当控分变电站出线断路器失败,则 返回重新选择可以执行的负荷转移编制预案,当控分变电站出线断路器成功后,则单条线路的负荷转移编制预案执行成功。由于单条线路可以具有多条负荷转移线路,即具有多个负荷转移编制预案,故在执行完一个相应的负荷转移编制预案后再按照优先级执行另外的负荷转移编制预案。
需要说明的是,在图4中,负荷转移编制预案可以分为2类,如优选预案和备用预案,其中,优选预案为按照负荷转移编制预案的优先级确定的待执行的负荷转移编制预案,备用预案为除了优选预案之外的负荷转移编制预案。在负荷转移编制预案满足第一预设条件时,执行负荷转移编制预案,按照先后顺序,先进行合环操作,若合环操作失败则从备用预案中选择可以执行的负荷转移编制预案,若合环操作成功,则继续执行解环操作,若解环操作失败,则执行其他负荷转移线路的负荷转移编制预案,若合环操作和解环操作均操作成功,则说明负荷转移编制预案执行成功,当所在线路的负荷转移编制预案执行完成后,则继续执行其他线路的负荷转移编制预案。
步骤204:对负荷转移编制预案执行成功后的结果进行实时监测,以获取负荷转移线路中的负荷率变化,并依据负荷率变化确定负荷转移线路中的重载线路,以及时提示调度人员依据重载线路进行二次负荷转移。
当负荷转移线路中存在重载线路时,则需要对其进行二次负荷转移,且二次负荷转移的过程与负荷转移线路第一次进行负荷转移的方法相同。
步骤205:当负荷转移线路中的负荷率变化满足第二预设条件时,将配电网运行方式还原为默认运行方式。
默认运行方式为配电网母线进行负荷转移前的运行方式。
需要说明的是,第二预设条件即为负荷转移编制预案执行成功。
本发明实施例提供的一种变电站母线负荷转移方法,变电站负荷转移编制预案的执行为多条线路负荷转移编制预案执行的并集,多条线路之间并发执行,互不影响,从而大幅度的提高了预案的执行速度,并通过实时监视配电网负荷转移线路的负荷率变化,有效的防止了配电网线路重载运行导致配电网发生停电事故,同时记录配电网中停电线路的恢复过程,且在检修工作结束后,智能完成配电网运行方式恢复。
请参考图5,其示出了本发明实施例提供的一种变电站停电应急快速应急处理系统的一种子流程图,可以包括以下步骤:
步骤301:判断负荷转移编制预案是否满足配电网运行方式,如果否,则执行步骤302;如果是,则执行步骤303。
步骤302:当负荷转移编制预案不满足配电网运行方式时,则重新编制负荷转移编制预案。
步骤303:当负荷转移编制预案满足配电网运行方式时,判断负荷转移编制预案执行后是否会导致配电网正常线路重载,如果否,则执行步骤304;如果是,则执行步骤305。
步骤304:当负荷转移编制预案执行后会导致配电网正常线路重载,则重新编制负荷转移编制预案。
步骤305:当负荷转移编制预案执行后不会导致配电网正常线路重载,则判断负荷转移编制预案执行后是否会导致检修区域带电,如果否,则执行步骤306;如果是,则执行步骤307。
步骤306:当负荷转移编制预案执行后会导致检修区域带电,则重新编制负荷转移编制预案。
步骤307:当负荷转移编制预案执行后不会导致检修区域带电,则执行负荷转移编制预案。
需要说明的是,在变电站工作时,在变电站中还存在对其设备进行检修的检修区域。
其中,第一预设条件即为负荷转移编制预案执行前需要满足的条件,即:负荷转移编制预案需要与配电网当前运行的状态相符合,负荷转移编制预案执行后不会导致配电网线路中的正常线路重载,负荷转移编制预案执行后不会导致检修区域带电。需要说明的是,在本发明实施例中,只有当负荷转移编制预案满足第一预设条件时,才可以继续执行该负荷转移编制预案。
与上述方法的实施例相对应,本发明实施例还提供了一种变电站母线负荷转移系统,请参考图6,其示出了本发明实施例提供的一种变电站母线负荷转移系统的一种结构示意图,所述系统可以包括:预案编制模块11、 定期预案校验模块12和事故预案执行模块13,其中:
预案编制模块11,用于获取配电网线路的负荷转移编制预案。
其中,预案编制模块11还可以包括:第一获取单元21、第二获取单元22和组合单元23,请参考图7,其示出了本发明实施例提供的一种变电站母线负荷转移系统的一种子结构示意图,其中:
第一获取单元21,用于分别获取配电网模型及配电网运行方式。
第二获取单元22,用于依据配电网模型及配电网运行方式获取配电网线路的预案。
组合单元23,用于将所有预案进行组合,以获取负荷转移编制预案。
预案编制模块11依据配电网SCADA系统获取配电网模型及配电网运行方式。可以理解的是,负荷转移编制预案是结合配电网模型及配电网运行方式形成的,其通过遍历变电站内所有10kV的配电网线路,利用拓扑搜索获取配电网线路的预案,再将所有的预案组合,便获得了变电站负荷转移编制预案。
定期预案校验模块12,用于判断负荷转移编制预案是否满足第一预设条件。
定期预案校验模块12定期遍历变电站内所有10kV线路,若负荷转移编制预案与当前配电网的运行状态不符,则认为该负荷转移编制预案无效,则提示用户重新编制线路的负荷转移编制预案。
需要说明的是,所谓负荷转移编制预案与配电网当前运行状态不符指负荷转移编制预案中控分开关当前运行状态已为分,或者控合开关当前运行状态为已为合。
事故预案执行模块13,用于当变电站母线需要转移,且当负荷转移编制预案满足第一预设条件时,执行合环预案,以对相应合环区域的线路进行环网运行;当合环预案执行成功后,执行解环预案,以对相应解环区域的线路进行解环运行。
本发明提供了一种变电站母线负荷转移系统,首先通过获取配电网线路的负荷转移编制预案,并判断负荷转移编制预案是否满足第一预设条件,当变电站母线需要转移,且当负荷转移编制预案满足第一预设条件时,执行合环预案,以对相应合环区域的线路进行环网运行;当合环预案执行成 功后,执行解环预案,以对相应解环区域的线路进行解环运行。与现有技术中逐点逐线按顺序实现变电站母线负荷转移的系统相比,本发明提供的一种变电站母线负荷转移系统,不仅缩短了负荷转移时间,还减轻了调度人员的工作量。
请参考图8,其示出了本发明实施例提供的一种变电站母线负荷转移系统的另一种结构示意图,在图6的基础上,还可以包括:异常状态监视模块14和运行方式恢复模块15,其中:
异常状态监视模块14,用于对负荷转移编制预案执行成功后的结果进行实时监测,以获取负荷转移线路中的负荷率变化,并依据负荷率变化确定负荷转移线路中的重载线路,以及时提示调度人员依据重载线路进行二次负荷转移。
可以理解的是,在执行完负荷转移编制预案后,还需要对执行后的效果进行实时监控,以及时发现配电网异常供电线路中负荷率的变化,进而及时发现重载线路。
需要说明的是,异常供电线路指变电站发生事故后配电网中停电线路的当前的供电电源。
运行方式恢复模块15,用于当负荷转移线路中的负荷率变化满足第二预设条件时,将配电网运行方式还原为默认运行方式。
默认运行方式为配电网母线进行负荷转移前的运行方式。
本发明实施例提供的一种变电站母线负荷转移系统,变电站负荷转移编制预案的执行为多条线路负荷转移编制预案执行的并集,多条线路之间并发执行,互不影响,从而大幅度的提高了预案的执行速度,并通过实时监视配电网负荷转移线路的负荷率变化,有效的防止了配电网线路重载运行导致配电网发生停电事故,同时记录配电网中停电线路的恢复过程,且在检修工作结束后,智能完成配电网运行方式恢复。
