Description

一种用于发电厂的远程备自投系统
技术领域
本发明涉及电力控制技术领域，更具体的说是涉及一种用于发电厂的远程备自投系统。
背景技术
备用电源自动投入装置(简称备自投)是当电力系统故障或其他原因使工作电源被断开后，能迅速将备用电源自动投入工作，或将被停电的设备自动投入到其他正常工作的电源，使用户能迅速恢复供电的一种自动装置。
目前，早电力系统中，备自投装置仅在本站端内实现，无法远距离实现两个及以上的不同站端内断路器控制，对于有发电厂接入的站端存在较大的电网风险，并导致发电厂“孤岛”效应。
发明内容
针对现有技术中存在的问题，本发明的目的在于提供一种用于发电厂的远程备自投系统，能够实现发电厂多个接入端的远方备自投，有效避免发电厂出现孤岛效应。
本发明为实现上述目的，通过以下技术方案实现：
一种用于发电厂的远程备自投系统，包括：服务端和多个备自投控制端，服务端与备自投控制端网络连接；
所述发电厂通过接入线路与多个电网站端连接，所述备自投控制端分别设在每个接入线路上；
所述备自投控制端，用于监测接入线路的电器参数并发送到服务端，根据服务端的控制命令执行控制接入线路的断开或闭合；
所述服务端，用于接收备自投控制端发送的电气参数，根据电气参数判断接入线路的运行状态，根据运行状态向相应的备自投控制端发送控制信号。
进一步，所述备自投控制端包括：采集单元、控制器、网络传输单元和断路器；
控制器分别与采集单元、网络传输模块和断路器信号连接；
所述断路器设在接入线路上，用于控制接入线路的断开或闭合；
所述采集单元，用于采集接入线路的模拟量和开关量，并发送到控制器；
所述控制器，用于将所述模拟量和开关量通过网络传输单元发送至服务端，并接收服务端下发的控制命令，根据控制命令控制断路器的断开或闭合。
进一步，所述服务端包括：
判断单元，用于将上传的模拟量与开关量分别与相应的阈值对比，根据对比结果确定相应的接入线路的运行状态；
数据库，用于存储每条线路的开关量阈值和模拟量阈值；
指令下发单元，用于根据接入线路的运行状态生成控制命令，并下发到相应的备自投控制端。
进一步，所述系统还包括站端断路器；所述站端断路器设在每个电网站端内，用于控制电网站端的开关，站端断路器与同一接入线路上的备自投控制端的控制器信号连接。
进一步，所述控制器具体用于：
将采集到的接入线路的模拟量、开关量和备自投控制端的唯一编码封装为电气参数数据包，经电气参数数据包通过无线网络上传至服务端。
进一步，所述判断单元具体用于：
利用预设的解密算法对电气参数数据包进行解包，根据备自投控制端的唯一编码在数据库中检索出对应的模拟量阈值和开关量阈值，若模拟量小于模拟量阈值且开关量小于开关量阈值，则接入线路的运行状态正常；否则，接入线路的运行状态异常。
进一步，所述指令下发单元具体用于：
若判断单元判定接入线路的运行状态正常，则生成闭合指令，并下发至相应的备自投控制端；
若判断单元判定接入线路的运行状态异常，则生成断开指令，并下发至相应的备自投控制端。
进一步，所述服务端还包括：
备用站端启动单元，用于当判断单元判定接入线路的运行状态异常后，根据异常接入线路上的备自投控制端的唯一编码在数据库中检索出备用的备自投控制端的唯一标识，并发送至指令下发单元；指令下发单元生成闭合指令并下发至备用的备自投控制端。
进一步，当所述控制器收到服务端下发的闭合指令后，同时控制备自投控制端内的断路器和同一接入线路上电网站端内的站端断路器执行闭合动作；当所述控制器收到服务端下发的断开指令后，同时控制备自投控制端内的断路器和同一接入线路上电网站端内的站端断路器执行断开动作。
对比现有技术，本发明有益效果在于：本发明提供了一种用于发电厂的远程备自投系统，利用远传、远控功能，能够同步实现多个电网站端之间不同断路器的投入和退出，将备用电源自动投入，保障电网安全稳定运行，并杜绝发生发电厂“孤岛”效应。
本发明根据电网实际运行方式和目标需求，对现有备自投装饰运行升级，结合电网站端的模拟量、开关量进行判定，利用远传、远控功能，实现地理位置较远的三个站端内断路器的投入和退出，将发电厂入网侧断路器断开，并合上预先设定的备用电网站端的进线侧开关，实现电网安全稳定运行，并杜绝发电厂“孤岛”效应，有效保护发电厂内电气设备。
由此可见，本发明与现有技术相比，具有突出的实质性特点和显著的进步，其实施的有益效果也是显而易见的。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
附图1是本发明具体实施方式的系统结构图。
具体实施方式
下面结合附图对本发明的具体实施方式做出说明。
如图1所示的一种用于发电厂的远程备自投系统，包括：服务端、多个备自投控制端和站端断路器，服务端与备自投控制端网络连接。其中，发电厂通过接入线路与多个电网站端连接，备自投控制端分别设在每个接入线路上。站端断路器设在每个电网站端内，用于控制电网站端的开关，站端断路器与同一接入线路上的备自投控制端的控制器信号连接。
所述备自投控制端，用于监测接入线路的电器参数并发送到服务端，根据服务端的控制命令执行控制接入线路的断开或闭合。
备自投控制端包括：采集单元、控制器、网络传输单元和断路器。控制器分别与采集单元、网络传输模块和断路器信号连接。断路器设在接入线路上，用于控制接入线路的断开或闭合。采集单元，用于采集接入线路的模拟量和开关量，并发送到控制器。
控制器，用于将所述模拟量和开关量通过网络传输单元发送至服务端，并接收服务端下发的控制命令，根据控制命令控制断路器的断开或闭合。具体来说：控制器将采集到的接入线路的模拟量、开关量和备自投控制端的唯一编码封装为电气参数数据包，经电气参数数据包通过无线网络上传至服务端。
所述服务端，用于接收备自投控制端发送的电气参数，根据电气参数判断接入线路的运行状态，根据运行状态向相应的备自投控制端发送控制信号。
服务端具体包括：判断单元、数据库、指令下发单元和备用站端启动单元。
判断单元，用于将上传的模拟量与开关量分别与相应的阈值对比，根据对比结果确定相应的接入线路的运行状态。具体来说：判断单元利用预设的解密算法对电气参数数据包进行解包，根据备自投控制端的唯一编码在数据库中检索出对应的模拟量阈值和开关量阈值，若模拟量小于模拟量阈值且开关量小于开关量阈值，则接入线路的运行状态正常；否则，接入线路的运行状态异常。
数据库，用于存储每条线路的开关量阈值和模拟量阈值。
指令下发单元，用于根据接入线路的运行状态生成控制命令，并下发到相应的备自投控制端。使用时，若判断单元判定接入线路的运行状态正常，指令下发单元生成闭合指令，并下发至相应的备自投控制端；若判断单元判定接入线路的运行状态异常，指令下发单元生成断开指令，并下发至相应的备自投控制端。
备用站端启动单元，用于当判断单元判定接入线路的运行状态异常后，根据异常接入线路上的备自投控制端的唯一编码在数据库中检索出备用的备自投控制端的唯一标识，并发送至指令下发单元；指令下发单元生成闭合指令并下发至备用的备自投控制端。
使用时，所有的备自投控制端根据接收的控制命令控制接入线路上电网站端的投入和退出。具体来说：当所述控制器收到服务端下发的闭合指令后，同时控制备自投控制端内的断路器和同一接入线路上电网站端内的站端断路器执行闭合动作；当所述控制器收到服务端下发的断开指令后，同时控制备自投控制端内的断路器和同一接入线路上电网站端内的站端断路器执行断开动作。通过这种联动控制的方式，能够有效减少电网端能量损失，并杜绝发电厂内发电机组的“孤岛”效应，为发电厂挽回了巨大的经济损失。
结合附图和具体实施例，对本发明作进一步说明。应理解，这些实施例仅用于说明本发明而不用于限制本发明的范围。此外应理解，在阅读了本发明讲授的内容之后，本领域技术人员可以对本发明作各种改动或修改，这些等价形式同样落于本申请所限定的范围。

5.根据权利要求4所述的用于发电厂的远程备自投系统，其特征在于，所述控制器具体用于：
将采集到的接入线路的模拟量、开关量和备自投控制端的唯一编码封装为电气参数数据包，经电气参数数据包通过无线网络上传至服务端。
6.根据权利要求5所述的用于发电厂的远程备自投系统，其特征在于，所述判断单元具体用于：
利用预设的解密算法对电气参数数据包进行解包，根据备自投控制端的唯一编码在数据库中检索出对应的模拟量阈值和开关量阈值，若模拟量小于模拟量阈值且开关量小于开关量阈值，则接入线路的运行状态正常；否则，接入线路的运行状态异常。
7.根据权利要求6所述的用于发电厂的远程备自投系统，其特征在于，所述指令下发单元具体用于：
若判断单元判定接入线路的运行状态正常，则生成闭合指令，并下发至相应的备自投控制端；
若判断单元判定接入线路的运行状态异常，则生成断开指令，并下发至相应的备自投控制端。
8.根据权利要求7所述的用于发电厂的远程备自投系统，其特征在于，所述服务端还包括：
备用站端启动单元，用于当判断单元判定接入线路的运行状态异常后，根据异常接入线路上的备自投控制端的唯一编码在数据库中检索出备用的备自投控制端的唯一标识，并发送至指令下发单元；指令下发单元生成闭合指令并下发至备用的备自投控制端。
9.根据权利要求8所述的用于发电厂的远程备自投系统，其特征在于：
当所述控制器收到服务端下发的闭合指令后，同时控制备自投控制端内的断路器和同一接入线路上电网站端内的站端断路器执行闭合动作；
当所述控制器收到服务端下发的断开指令后，同时控制备自投控制端内的断路器和同一接入线路上电网站端内的站端断路器执行断开动作。
