Description

电力配电网动态管理的方法和系统
技术领域
本发明涉及电力配电网的动态管理领域。
本发明更确切地涉及一种具有多个供电相的电力配电网的动态管理的方法和系统，提供各相的至少一个电参数的评估。
背景技术
在电网中，电力终端配电是将低电压(LV)从MV/LV(中级电压/低电压)变电站传输到低电压用户(数量上大约一百个)，特别是居住的寓所。MV/LV变电站提供几个馈电线(数量上大约4到10个)。每个馈电线以呈现几个单相或三相连接的辐射状结构的形式布置。位于MV/LV变电站中的LV面板分配功率给不同的馈电线，其中的每一个可通过保险丝或断路器保护。
低电压功率网很密，有时在空中，有时在地下，混合变化的设备以及不同年代的电缆。它们由电力公司操作，其中的一些具有跨越一个世纪或者更久的历史，期间电网经历了修改，扩展，或者分离。这些电网在技术上是简单的，几乎不会出现故障，并且因此很少存档，或者几乎不存档。
其他两个因素结合到上下文中。第一，电力部门放松管制影响涉及的参与者的分离。第二，配电网由具有垄断地位的电力分配者接管，但是发现他们自身由国家监管机构的要求所约束。后者对他们的分配者施加服务质量目标，根据每个连接的用户观察的停电的时间和数量来测量该目标。这些目标被约束并且如果它们不受重视时会导致罚款。于是配电者因此需要非常精确的停电数据以及准确的信息以更好地定位可能发生的错误和故障。
进一步地，仍然是放松管制的情况下，多个国家已决定安装智能仪表，避免需要派出人员来执行仪表的读取。取决于监管环境和配电者，选择不同结构来执行远程仪表读取操作。在这些结构的某些中，特定配电者已决定在每个MV/LV变电站中安装数据集中器。后者从每个连接的仪表收集数据。计量数据通过线载波电流或者通过无线电装置以固定的频率(大约半个小时到一天)接收。数据集中器然后通过另一通信装置发送这套测量数据给更高一级。来自于每个仪表的计量数据在每个MV/LV变电站中几乎是实时可用的。
对于配电板，馈电线的三相之间的低电压电网的负载平衡对技术损耗的水平，电网正常运行时间因素和服务的延续性具有相当大的影响。然而该问题仍未解决，特别是以简单、经济和有效的方式解决。
服务的延续性和电压等级的兼容例如被馈电线中性线所通过的电流所影响，容易造成在随后引起的一些连接的损坏的潜在增长。
由于在电网分布的发电机(光伏发电，风力发电，电池，以及其他)的电流的大量并入，这可能周期性地导致电网的饱和，使得所述问题更为严重，因而影响到电网的增强。
发明内容
发明目的
本发明的目的是提供一种使得先前出现的问题被补救和改进现有技术的解决方案的用于配电网的大型管理的方法。
特别是，本发明的第一目的是提供一种使能各相上传输的功率被分配的管理方法。

在优选实施例中，动态管理方法执行电网不同相的负载平衡，评估和配电步骤以周期性方式自动实施。
优选地，在配电步骤期间，用于不同相的负载分配和/或输入给不同相的配电的标准被配置来获得体现在最小化电网各相之间的负载不平衡的平衡。

具体实施方式
本发明将在对电力配电网的应用中进行描述，例如从MV/LV(中级电压/低电压)配电变电站到低电压用户(数量上大约100个)特别是住宅的低电压LV型。MV/LV变电站提供多个馈电线(数量上大约4到10个)，在馈电线之间电力在变电站等级中分配。每个馈电线主要由三个供电相L1，L2，L3和中性相N构成，和以辐射状结构的形式布置，呈现用于每个用户到馈电线的连接的多个单相或三相线。
由各相和/或给电网的一个或多个相注入电力的发电机(光伏发电、风力发电、电池(特别是电动车辆的电池)，和其他)的一个或多个供电的消耗能量的负载被设置在电网中。
为了监测低电压用户的消耗，单相或三相连接传统上配置巧妙或智能型电力消耗仪表。同样，由发电机输入电网的功率的监测通过分配在和连接到电网的生产仪表实施。
每个仪表(不论是功耗仪表还是功率生产仪表)被配置为规律地传递消耗和/或生产数据给与之连接的MV/LV配电变电站。位于电网(例如在变电站中)的数据集中器收集来自于各仪表的数据和处理每个连接仪表的连续读数。计量数据以规律的频率(大约半小时到一天)有利地通过线载波电流接收，但也通过无线电装置发送。
消耗仪表能进一步额外实时或者以周期性的方式发送信息使能数据集中器确定给定相(在涉及三相连接的情况中则重复地针对三相L1，L2，L3)的电压，特别是通过连接到该相的仪表的电压等级的周期性检测来实现。换句话说，各仪表对集中器通信电压等级，集中器从位于电网不同位置产生的结果的集合中编辑每相的电压文件(profile)。
在前面，应知晓数据集中器，通过同分布在电网上的不同仪表(消耗和/或生产仪表)经由线载波电流或无线电装置通信，构成使得各相的至少一个电参数被评估或确定的元件，电参数例如是每个的功率等级和/或由每个相供电的负载和/或由发电机给每个相供电的输入功率。
本发明的基本特征体现在如下事实中，在这种环境中，提供具有用于实施管理方法的硬件和/或软件装置的电网的动态管理系统，其将进一步更详细地描述，特别是至少在电参数评估元件的帮助下，而且也利用设计来以动态方式调整负载对各相的电连接和/或以动态方式调整发电机到各相的电连接的配电元件。
下面将更好地理解，配电元件特别包括至少一个选择器开关(图4)，使得至少一个负载被分配的电网的相L1，L2，L3可选择地改变。作为补充或者替代，至少一个选择器开关可被提供在电线层或者在发电机和电网的各相之间的连接中，选择器开关使输入到每个相的功率(能量或电流)的比例被调节。连接到发电机的选择器开关可被集中在特别是光伏发电生产的情况下的逆变器中，并且可以二进制或者成比例的方式执行在各相之间的选择的或者结合的调节。连接负载和连接发电机的选择器开关具体受评估元件(特别是数据集中器)所控制。
因此，在各相的至少一个电参数的评估步骤之后，各相上发送的功率的分配步骤可以根据评估步骤的结果来执行，该评估步骤通过执行负载对各相的电连接的动态调整和/或发电机对各相的电连接的动态调整来实现。
包括之前所述的参数评估和功率分配的步骤的管理方法使能实现至少一个给定相的电压调节和/或电网的不同相上的负载平衡。
在相电压调节的情况下，评估步骤中的评估的参数之一因此是相的电压等级，其他参数是由各相供电的负载值和/或源自发电机的输入功率的值。
配电步骤不必自动地以周期方式实施，而是更适合当评估的相电压低于第一预设门限值或者高于第二预设门限值时被实施。具体地，门限值可从高和低极限值中建立，其中针对极限值应用了勾画目标间隔的安全余量。
一个有利的策略来控制部件是以这样的方式，在相电压低于第一预设门限值的情况下，配电步骤包括将全部或部分连接到相同相的负载分配至电网的其他相和/或包括将连接到电网的其他相的发电机的全部或部分功率分配到这一相。
另一方面在负载平衡的情况下，评估和配电步骤有利地以周期性方式自动实施，适合于具有在电网和负载和/或发电机之间的电连接的动态调整。
为了确保在各相L1，L2，L3上的功率分配，用于分派负载给不同相和/或分配输入给不同相的功率的标准在配电步骤期间被配置以获得体现在最小化电网的各相之间的负载不平衡的平衡，这些不平衡之前由评估元件(特别是数据集中器)所确定。配电包括对于负载连接的选择器开关和/或发电机连接的选择器开关的适当控制。
在对于至少一个给定相的电压调节和不同相上的负载平衡的需求同时出现的情况下，给定相的电压调节有利地优先于不同相上的负载平衡。
上述解释使之可以理解，所介绍的用于负载和发电机的选择器开关的操作确保各相和相应的负载和发电机之间的电连接的必要的动态调整。这些动态调节通过选择器开关的适当控制的方式来控制，例如由数据集中器来管理。
图1示出了发电机到各相L1，L2，L3的电连接的动态调整。数据集中器1评估(通过测量线圈2，3和4)来自变压器变电站5的馈电线的每个相的负载。逆变器7和8通过线载波电流信号CPL通信它们的生产到集中器1。这些相执行评估步骤。集中器1然后能通过执行计算来评估各相之间的不平衡并且给出将输入到逆变器7和8的每一相的电流的分配顺序，其包括用于该目的的配电选择器开关(相应的12和11)，该开关用于连接到相。选择器开关通过集中器的适当控制，三相逆变器能够输入正确比例的电流或功率给每个相。特别是当在给定馈电线的层级所产生的功率大于或等于不平衡的功率时，系统能实时确保良好的平衡。逆变器例如由光伏板9和10供电。
用于发电机连接的选择器开关可具有与那些以选择适配方式用于连接负载到各相的选择器开关相同的性质(见图4标示的元件14)。选择器开关可包括来自集中器的控制信息的接收器(或读取器Reader)，其发送控制信息给处理器(processor)，其传递关联到不同相的多个启动器(actuator)的命令指令。
图7说明用于执行各相之间的负载平衡的动态调整的相同的情况，选择器开关为生产仪表15和电气发电机16。通过分配生产的逆变器17来执行平衡，其能够从DC总线中重新给三相中的每相注入更多或更少的功率。仪表是三相用户的仪表18，它周期性地将它们的功率指标通信给位于变电站5中的数据集中器。三相生产仪表15，例如由光伏板供电，以同样的方式将它们的产出通信给集中器，能从这些功率指标中推断周期上所产生的或者所消耗的平均功率。在各相之间所消耗的平均功率的较大差异(例如大于30％)保持最小两个周期的情况下，集中器发送命令给逆变器17，使得各相之间的平衡在配电变电站5的等级上改进。
图2显示了在电网不同相上的负载平衡过程中的负载到各相的电连接的动态调整。数据集中器1评估来自于变压器变电站5的馈电线的每个相的负载(通过测量线圈2，3和4)。集中器1因此能通过计算评估各相之间的不平衡。当不平衡达到固定的预设门限值时，集中器1发送询问给装配有选择器开关11和12的仪表7和8，选择器开关11和12对仪表供给瞬时功率。集中器1然后能计算每相的最佳的仪表配电，以便通过在不同相上分配负载来尽可能地减少不平衡，以最终分配不同相上的功率。用于这个的集中器1以适当的方式执行每个选择器开关14的控制以获得尽可能接近的各相之间的平衡。选择器开关14以线性载波电流的方式同数据集中器1通信。
图5和6描述了通过供电相的控制来执行各相间负载的平衡的动态调整的相同的情况。在图5中，选择器开关14位于来自于消耗仪表(未示出)的线路侧，消耗仪表因而安装在位宅楼宇6和选择器开关14之间，后者并且能够用于供电到多个住宅6(这里数量上为3个)。由选择器开关14获得平衡，开关14可以在三个可能的相之间切换以执行单相馈电线的供电。单相用户仪表周期性地将它们的能量指标通信给位于变电站5中的集中器，并且集中器能够推断周期上的平均功率。在各相之间所消耗的平均功率的较大差异(例如大于30％)保持超过最小两个周期的情况下，集中器1发送命令给逆变器14使得各相之间的不平衡在配电变电站的等级中改进。
在图6中，另一方面，选择器开关14位于来自三相消耗仪表18的负载侧，并且对多个负载19(比如采暖，换流器，灯或者其他)供电。选择器开关14在三相之间切换来执行平衡。操作原理类似于图5中的内容，而不同在于安装在用户楼宇的选择器开关不再位于配电网中，即来自于仪表18的线路侧。该解决方法使得用户最优化其供电订购的订购功率。如果用户具有MV/LV变压器，也使得不平衡有关的损耗被限制。
应知晓在图5和6的情况下，选择器开关的置换动作导致大约7ms的相移，这对负载19的操作不是不利的，并且仍然位于依据电网管理标准EN50160和负载标准61000-2-4的可接受的掉电的范围内。
图3最后显示了在至少一个给定相的电压调节过程中负载到各相的电连接的动态调整。住宅6的仪表13将它们的电压等级传送给集中器1，集中器1编辑每相的电压文件。当电压接近高或低极限值，下降到低于第一预设门限值而高于第二预设门限值，集中器查询与之通信其瞬时功率的仪表。当电压降落低于第一预设门限值时，例如在电网终端，集中器1传送命令给连接到相同相的选择器开关来将自身分配给其他两相。所述电压调节过程优先于图1，2的负载平衡。
本发明最终涉及包括当程序在计算机上执行时，适合于执行上述步骤的计算机程序编码装置的计算机程序。
