Description

配电台区移动监测平台装置、系统及方法
技术领域
本公开涉及配电台区移动监测平台装置、系统及方法。
背景技术
根据《国家电网有限公司关于印发公司2020年重点工作任务的通知》(国家电网办2020 74号文)和《国网设备部关于印发2020年设备管理重点工作任务的通知》(设备综合2020 14号)要求，为提高供电可靠性和供电服务质量，推进能源互联网高质量发展，各地区应大力发展智能配电网，打造优质智能配电网示范区，提升营配贯通水平。
低压配电网是电网结构中“最后一公里”盲区，营配贯通水平低、低压设备信息透明度差、计量数据挖掘深入性不足等问题，都是打造智能配电网道路上的绊脚石。而低压台区的核心问题，就是台区拓扑结构信息缺失。缺少台区拓扑结构，智能台区中基于台区拓扑实现的低压故障定位研判与主动抢修、台区线损异常分析、台区窃电治理的深化功能均不能应用。
现阶段，台区拓扑识别技术并不成熟。新建台区拓扑不能直接生成，需要人工摸排绘制，给一线人员带来巨大的工作量和工作压力。现阶段技术中，有依据HPLC(宽带载波)智能电表上传数据完成户变关系识别，但无法识别分支箱和用户表箱之间的拓扑关系。低压拓扑有依靠综合配电柜-分支箱-用户表箱均加装感知终端，依靠载波、4G、微功率无线等通信方式实现台区各级之间信息互通，生成台区拓扑，但此方法资金投入过大，台区加装设备过多，实施困难，且变向增加故障点，降低供电可靠性，给一线人员运维增大压力。
拓扑识别方法还分为人工识别、停电识别两种方法。其中人工识别为班组员工依靠配电抢修经验，手工绘制台区拓扑，这种方法存在效率低、成本高、准确率低，现场拓扑变更后需要重新识别的问题。停电识别为人工拉合开关，依靠用户停电区域识别台区拓扑。这种方法效率低、成本高，不利于提升客户优质服务，现场拓扑变更后需要重新识别。
发明内容
为解决上述方案中，技术实用性差、投资金额大、拓扑生成不完全的问题，本公开提出一种配电台区移动监测平台装置的研制和使用方法，实现低压台区拓扑自动生成。
第一方面，本公开提供了一种配电台区移动监测平台装置，包括：采集模块和信号注入模块；
所述采集模块包括若干个分支路监测终端，所述分支路检测终端对配电数据进行采集；
所述信号注入模块包括纯容性负载，纯容性负载采用多次短时投切方式运行，并通过控制投切的时长和通断来组成特定的无功状态序列，通过无功状态序列进行信号注入实现拓扑打点。
第二方面，本公开还提供了一种配电台区移动监测平台系统，包括：移动终端、配电终端和如第一方面所述的配电台区移动监测平台装置，移动终端与配电终端和配电台区移动监测平台装置通讯连接，配电台区移动监测平台装置与配电终端通讯连接。
第三方面，本公开还提供了一种如第二方面所述的配电台区移动监测平台系统的应用方法，步骤包括：
将台区侧的配电台区移动监测平台的台区位置信息、各进出线回路信息配置完成；
进行全部设备组网，待全部设备组网成功移动终端发送拓扑打点信号至配电台区移动监测平台；
配电台区移动监测平台接收到拓扑打点信号，通过信号注入模块投入电容进行拓扑打点，指示灯用于显示是否成功投入电容；
台区所有点全部拓扑打点成功后，移动终端传输结束信号至配变终端，配变终端生成拓扑信息。
与现有技术对比，本公开具备以下有益效果：
1、本公开采用包括纯容性负载的信号注入模块，纯容性负载采用多次短时投切方式运行，并通过控制投切的时长和通断来组成特定的无功状态序列，通过无功状态序列进行信号注入实现拓扑打点，造价成本低，节省费用，普及率高，可多次应用，代替传统固定式安装的LTU打造的智能台区，经济方面：通过对低压台区运行设备的在线监测，保证了低压电网的安全稳定运行，避免了设备故障运行造成的电力资产损失以及由此引发的安全事故。低压停电故障自动上报功能应用解决了以往低压故障处理不及时带来的时间成本。智能低压配电网的建设减轻了一线员工的工作量，提高了劳动效率，降低了低压故障判断的成本；相比于传统的监测末端产品，减少了设备投入，节省了建设成本。
2、社会效益方面：提高了低压台区运行可靠性，减少故障事件对用户的影响，缩短用户停电时间，提升客户满意度，体现了电网公司以客户为中心的服务理念；利用“互联网+”技术手段提供全面分析，及时发现故障，减少停电事故。
3、管理效益方面：①解决了目前低压配电网自动化程度低，对于运行状况无法及时感知的问题，将低压配电网管理现状从“被动管理”提升为“主动管理”，提升了供电可靠性；②为运行检修管理部门实现低压配电台区的信息化、智能化管理提供了先进的技术手段，并且能够提供营销客户座席所需的故障信息，以便对故障情况及时做出反应。

实施例1
如图1所示，本公开开发一种配电台区移动监测平台装置，包括采集模块和信号注入模块；
所述采集模块包括若干个分支路监测终端，所述分支路检测终端对配电系统数据进行采集；
所述信号注入模块包括纯容性负载，纯容性负载采用多次短时投切方式运行，并通过控制投切的时长和通断来组成特定的无功状态序列，通过无功状态序列进行信号注入实现拓扑打点。控制投切的通断即为控制投切的有无。
信号注入模块原理图如图3所示：
接触器电容投切装置由接触器和电阻切合电路组成。图中1为电阻，抑制电容器回路冲击。2为主触头，用来切合回路。3为容性负载，用来组成特定的无功状态序列。投入时，电阻切合电路提前接通，电流流经电阻向电容器充电，电阻抑制了电容器的合闸涌流，随后主触头闭合，承载了电容器的正常工作，同时短接电阻，完成电容器的投入过程。切除时，主触头先断开，电阻切合电路延时断开，抑制了电容器切断时的操作过电压，完成电容器的切除过程。
进一步的，还包括外箱，所述外箱为手提箱式，外箱上设有指示灯，所述指示灯包括提示信号注入成功指示灯和拓扑成功指示灯。
进一步的，所述采集模块可选择现有型号NX800D-T。采集模块具备多路电量采集功能，具体配置有六路，用于采集三相电压电流、有功功率、无功功率、视在功率和电网频率。采集模块实时测量三相电压电流的谐波畸变率以及相应的2-21次谐波。采集模块计量三相有/无功电能，正反向谐波电能。采集模块测量三相有功和无功的实时需量，并能记录三相有功无功最大需量及其发生时间。
所述采集模块设有多路电量采集电路，具备多路电量采集功能，用于采集三相电压电流、有功功率、无功功率、视在功率和电网频率。
所述采集模块还设有谐波电能获取电路，用于计量三相有/无功电能，正反向谐波电能。
所述采集模块还设有三相有功和无功检测电路，用于采集模块测量三相有功和无功的实时需量，并能记录三相有功无功最大需量及其发生时间。
所述采集模块还设有谐波检测电路，用于实时测量三相电压电流的谐波畸变率以及相应的2-21次谐波。
进一步的，所述配电系统数据包括低压台区配电系统的主回路、分支回路的三相电压和多路电流数据；通过内部计算，获得分支线路上的完整的电能量数据及电能质量数据、设备运行状态信息，同时可采集末端负荷的电能量数据，所有的数据可以在终端内部汇总、计算、分析、存储。
所述外箱设计多组电流CT接口，CT可配置多种电流等级，400A/5A、600A/5A等各种不同规格互感器可适配各应用场景。
进一步的，还包括通讯模块，所述通讯模块支持多种上下行通信方式，上行通信可选用RS-485总线、电力线载波、蓝牙和4G等四种方式，下行通信信道为RS-485总线方式。配电台区移动监测平台装置通过通讯网络与移动终端和融合终端连接。融合终端通过接收配电台区移动监测平台装置拓扑打点数据，实现低压台区拓扑自动生成。
具体的，配电台区移动监测平台装置装置通过开拆卸式LTU(分支线路监测终端)，能对低压台区配电系统的主回路、分支回路的三相电压和多路电流数据同时进行采集、处理和储存，通过内部计算，获得分支线路上的完整的电能量数据及电能质量数据、设备运行状态信息，同时可采集末端负荷的电能量数据，所有的数据可以在终端内部汇总、计算、分析、存储。通过和上一级的融合终端(TTU)及主站配合，可实现整个低压台区的台区拓扑自动生成、台区负荷自动识别、线损计算功能。该装置配置通信模块，支持多种上下行通信方式，上行通信可选用RS-485总线、电力线载波、蓝牙和4G等四种方式，下行通信信道为RS-485总线方式。
配电台区移动监测平台装置，可带电安装拆卸，手提箱式设计，集成度高体积小，质量轻，便于携带移动。在场景应用中，可在采集完某监测点信息后拆除带走，前往下一监测点进行数据采集。装置内部采用高性能的单片机平台和高精度的计量平台，能采集多个回路的电量数据及电能质量数据，同时还具有数据计量、设备状态监测、数据通讯的多种功能，因此也适合安装在空间不大的分支箱等台区配电末端环境，用于低压台区配电系统末端的多个回路及负荷的数据采集与监测。
配电台区移动监测平台装置主要分为采集模块，信号注入模块，外箱和工装的设计工作。
采集模块设计：采集模块具备多路(可配置6路)电量采集功能，可实时采集三相电压电流、有功功率、无功功率、视在功率和电网频率。可实时测量三相电压电流的谐波畸变率以及相应的2-21次谐波。可计量三相有/无功电能，正反向谐波电能。测量三相有功和无功的实时需量，并能记录三相有功无功最大需量及其发生时间。
为实现自动拓扑功能，采集模块还应能准确采集到拓扑产生的注入信号。
信号注入模块设计：自动拓扑识别选用高频纯阻性(或阻感性)负载，纯容性负载等其它信号源。
阻性负载易获取，但线路上本来就是阻感性负载，注入的信号相位容易和线路负载搞混，接收信号的采集装置就不容易感应注入信号，注入就会失败。
而采用纯容性负载能有效避开线路原有负荷干扰，采用多次短时投切，控制投切的长短和通断，组成特定的无功状态序列，对电网的影响几乎可以不计，具有良好的可识别性和抗干扰能力。
外箱和工装：装置的外箱类似于手提箱设计，要方便携带，采用工程塑料，高防护等级。
外箱上需设计指示灯，提示信号注入成功以及拓扑成功指示灯。
外箱需设计多组电流CT接口，CT可配置多种电流等级，400A/5A、600A/5A等各种不同规格互感器可适配各应用场景。
远程通讯和本地蓝牙通讯方案：
配电台区移动监测平台由于其功能实现特殊性，需要从一处拓扑节点移动到另外节点，拓扑过程不是连续的，该装置与边缘计算装置需要有可靠的交互机制，来实现通知和应答环节。并且配电台区移动监测平台需要设置和配置参数，也需要对其进行交互操作。设计一款具备与配电台区移动监测平台和配变终端远程通讯的设备就很有必要。
可使用平板来实现交互流程。
因台区环境复杂性，且范围较广，采用微功率无线可能无法满足配变终端与平板的通讯需求。
建议使用4G远程通讯实现台区交互。
边缘计算网关本身不带固定ip供远程连接，配变终端要借助4G网关连接到云，平板也同时连接到云，在云上建立服务，使平板和配变终端实现远程交互，实现功能配置和控制命令下发。
配电台区移动监测平台与平板间可选用RS485，以太网口，蓝牙等方式实现交互方案。
串口和以太网口类似，都需要接线需要硬件支持，平板可采用串口转USB，配电台区移动监测平台可使用以太网口转串口。功能都能实现，但受限于接线，在某些应用场合下可能不是很方便。因此，更建议使用蓝牙接口。平板一般自带蓝牙，配电台区移动监测平台可配置蓝牙转串口。
通过蓝牙接口来实现平板与装置间的交互。

实施例3
一种配电台区移动监测平台系统的应用方法，包括：
将台区侧的配电台区移动监测平台的台区位置信息、各进出线回路信息配置完成；
进行全部设备组网，待全部设备组网成功，移动终端发送拓扑打点信号至配电台区移动监测平台；
配电台区移动监测平台接收到拓扑打点信号，通过信号注入模块投入电容进行拓扑打点，指示灯用于显示是否成功投入电容；
台区所有点全部拓扑打点成功后，移动终端传输结束信号至配变终端，配变终端生成拓扑信息。
具体的，拓扑自动识别方法：
过去的固定打点设备只需要在台区所有节点安装完LTU(注入式监测单元)，TTU处下发拓扑指令，各节点依次拓扑打点，等待所有节点打点完成后，就可生成拓扑。该过程只需要录入一次LTU信息，就可交给TTU/主站控制拓扑命令，并不需要交互环节。
配电台区移动监测平台台区有区别于固定拓扑打点注入的设备，整个拓扑过程有多个交互环节，需要人为控制和下发命令，具体流程如下。
1)先将台区侧的配电台区移动监测平台配置好
平板配置配电台区移动监测平台相应的台区位置信息,如1#分支箱，3层户表箱，配置各进出线回路信息，如1单元3层户表箱：出线1：202004211001(或1#分支箱：出线1：1单元总表箱)，该信息配置录给配电台区移动监测平台，平板将信息同时上传至配变终端(更新给配变终端的是配电台区移动监测平台的通讯地址，安装位置，和各支路名称)。更新配变终端的档案。
2)平板显示组网状态，等待直至全部设备组网成功。
在分支处/表箱处，准备拓扑打点。
3)平板启动该配电台区移动监测平台开始拓扑打点
平板上显示配变终端已下发拓扑打点命令。
4)配电台区移动监测平台接收到拓扑打点信号，投入电容，面板上指示灯能显示已投入电容。
5)平板上显示哪些设备接收到拓扑打点信号。
若有其它配电台区移动监测平台接收到拓扑打点信号，打点的配电台区移动监测平台显示打点成功(配变终端通知配电台区移动监测平台)。如失败(除非是台区侧出线打点，不然所有子节点拓扑打点都应该会有设备接受到拓扑打点信号)，可继续通过平板下发拓扑打点命令，直至拓扑打点成功。
携带配电台区移动监测平台换下一个位置节点继续1-5步骤
此时配电台区移动监测平台地址不变，不用重新组网，但平板录给配变终端/配电台区移动监测平台的信息(位置信息和各支路信息)不同，以此区分两次拓扑打点位置(必须要更新信息，来区分两次拓扑打点位置不同，不然配变终端无法判断两次打点有什么区别，会认为有可能是同一位置重复拓扑打点)。
7)台区所有点全部拓扑打点成功后，平板通知配变终端打点已结束，请生成拓扑；
针对整个拓扑流程，需要开发各个交互环节的通讯协议和流程控制，确保各环节尽量少出错，出错也不会陷入死循环或崩溃，能尽可能效率准确的完成整个流程。
