Description

同一智能电子设备中的多对象保护、控制和监视
技术领域
【0001】本发明涉及电力传输和分配以及对组成电力传输和分配系统的元件的保护、控制和/或监视。
背景技术
【0002】用于电力传输和分配的系统的元件，其中包括诸如母线、输电线、变换器、断路器等等，通常由智能电子设备(IED)进行受控的监视、保护和控制。IED采集关于元件的信息并且检测系统中的事件和干扰。这样的监视、保护和控制对于保持电力的可靠供给是必须的。电力系统的破坏可以导致对商业和人类的破坏。
【0003】传统上，一个IED仅处理一个受保护或受控制的电力系统主对象(primary object)。另外，传统上，要求IED仅处理保护或控制。在一些情况下，对于由一个IED控制的一个电力系统主对象，进行电力传输和次输电(sub-transmission)时既有保护，又有控制。在其它情形下，进行电力的分配时可以将保护和控制集成于一个IED中而进行。然而，仍仅针对一个电力系统主对象。
发明内容
【0004】本发明包括：一个IED可以进行多个电力系统主对象的保护、控制或监视中的至少一种。
【0005】本发明的一个实施例提供一种智能电子设备，该智能电子设备包括输入/输出模块，该输入/输出模块包括被配置成将所述智能电子设备连接到多个电力系统主对象的多个模拟和数字的输入连接和输出连接。所述输入/输出模块接收来自所述多个电力系统主对象的输入，并且提供输出到所述多个电力系统主对象。干扰记录模块记录来自多个通道的多个干扰。处理模块操作地连接到所述输入/输出模块和所述干扰记录模块。所述处理模块包括处理器，该处理器操作地分析来自所述多个电力系统主对象的输入，用于进行所述多个电力系统主对象的集成的保护、控制或监视中的至少一种。
【0006】本发明的实施例也涉及包括所述IED的系统。根据本发明的方法进行所述多个电力系统主对象的保护、控制或监视中的至少一种。
【0007】根据描述、附图和示例，本发明的其它目的和优点以及示例实施例的结构和功能将很清晰。
附图说明
【0008】根据下面对本发明的一个示例性实施例的更具体描述，本发明的前述和其它特征及优点将很明显，并如在附图中示出的，其中相同附图标记通常表示相同、功能类似和/或结构类似的元件。
【0009】图1示出根据包括本发明的IED的系统的实施例的简单示意图；
【0010】图2示出控制双断路器的IED的实施例的示意图；
【0011】图3a和3b示出分别解释说明用于保护、控制和监视六个馈电线的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图；
【0012】图4a和4b分别解释说明用于保护、控制和监视两个干线的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图；
【0013】图5a和5b示出分别解释说明用于冗余地保护、控制和监视两个干线的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图；以及
【0014】图6a和6b示出分别解释说明用于保护、控制和监视多个不同电力系统对象的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图。
具体实施方式
【0015】以下详细讨论本发明的实施例。在描述实施例时，为了清楚，将使用特定术语。然而，本发明无意受限于所选择的特定术语。尽管对特定示例性实施例进行了讨论，但应当理解，这仅用于说明解释目的。相关领域的普通技术人员可以认识到在不脱离本发明的精神和范围的情况下可以使用其它部件和配置。
【0016】在电力传输和分配领域中，并不知道使用单个智能电子设备来提供多个电力系统主对象的监视、保护和控制中的至少一种。特别是在高电压应用中更是这种情况。电力系统对象可以包括电力传输和/或分配系统的元件，诸如断路器、继电器、仪表、隔离开关、切换开关、分接开关和用在电力传输、次输电和/或分配中的其他设备。IED适用于高电压应用可以存在的环境，诸如高电磁场和大的温度变化。IED满足保护、监视和控制电力系统和/或设备的主要任务，且其通常实时执行这些任务。
【0017】具有高性能处理器的现代技术使得执行集成在一个IED中的对一个或多个电力系统主对象的保护、控制和监视成为可能。然后通过减少装置中的IED的数目可以节省成本。附图提供了将多个电力系统主对象的保护、控制和监视分配给一个IED的示例。
【0018】本发明包括：一个IED可以使用其模拟和二进制电路连接到两个或更多电力系统主对象，用于对电力系统主对象进行保护和/或控制和/或监视。通过根据遵循n-1准则从应用库来示例说明每个IED的功能性，很容易将公用事业电力系统保护和控制方式所需的冗余和无关性包括在IED中。由于模拟和二进制通道在IED中的限制，这在以前是不可能的，而在一些现代IED中已不再存在所述限制。
【0019】根据本发明，来自两个电力系统主对象或者多个电力系统主对象的信息可以被分配给一个IED。这可以减少装置所需的IED的数目。因此，使用本发明可以节省相当大的成本。
【0020】图1表示根据本发明的包括IED 100的系统的实施例的简单示意图。图1所示的实施例包括处理模块，该处理模块包括中央处理单元(CPU)。根据本发明的IED典型地包括仅一个CPU。CPU可以是多核CPU。通常，CPU具有足够快的时钟速度，可以在电力系统中有效的监视、控制和保护对象。根据一个实施例，CPU具有至少600MHz的时钟速度。处理模块也可以包括存储器。根据一个实施例，所述存储器包括256Mb DRAM和64Mb闪烁存储器。包括在处理模块中的存储器容量可以根据需求而变化。
【0021】IED还包括操作地接收来自IED正在监视、控制和保护的电力系统对象的输入并且将输出发送给该电力系统对象的输入/输出模块。输入/输出模块可以包括多个输入/输出板，以允许IED被连接到多个电力系统对象。根据一个实施例，输入/输出模块包括14个输入/输出(I/O)板。输入/输出模块可以包括二进制输入和输出。根据其它实施例，输入/输出模块包括16个二进制输入、24个二进制输出或8个输入和12个输出。这些仅为示例，并且输入/输出模块可以按照应用所需而包括尽可能少或尽可能多的输入和/或输出。
【0022】图1所示的IED的实施例也包括逻辑单元5以及跳闸和信号矩阵模块(trip and signal matrix module)7。逻辑单元可以采集二进制信号并且将它们组合成适当信号用于在IED中的内部使用。跳闸和信号矩阵模块可以执行信号调节，以使信号与通信接口相适配并且/或者确保信号位于正确的电压输入/输出范围内。跳闸和信号矩阵模块可以采集来自许多保护功能元件的信号并且将它们组合成适当的输出信号。这尤其可以为了在IED外部的使用而对信号进行适配。逻辑单元以及跳闸和信号矩阵可以操作地连接到输入/输出模块、CPU和远程保护通信模块、存储器、人机界面和监视通信模块。
【0023】图1所示的IED的实施例还包括信号处理单元9。信号处理单元可以帮助分析信号、选择处理哪些信号并且可能过滤一些信号并且允许其它信号传送到通信接口。例如，所述滤波器可以利用信号处理中所使用的任何离散滤波器过滤期望的频率或频带。离散滤波器的一个示例是离散傅里叶变换(DFT)。
【0024】可以使用的滤波器的另一个示例是从信号中过滤噪声的滤波器。这样的滤波器的一个示例是均方根(RMS)滤波器。信号处理单元可以操作地连接到CPU、远程保护通信模块、存储器、人机界面和监视通信模块以及模拟/数字转换器11。
【0025】模拟/数字转换器可以连接在信号处理单元与用于测量IED正在监视、控制和/或保护的主电力系统对象的参数的电路之间，所述电路诸如为电压和电流测量电路19，其测量至少两个电力系统主对象的相电压和相电流。模拟/数字转换器可以包括多个模拟通道。一个实施例包括24个通道。模拟/数字转换器可以运行在允许IED执行其功能的任何频率。图1所示的示例性实施例运行在5kHz的频率。
【0026】根据本发明的IED也可以包括远程保护通信模块13。该模块可以操作地连接到信号处理单元、逻辑单元以及跳闸和信号矩阵模块。这些元件可以被包括在用于故障的保护方案或反应中。
【0027】为了允许显示从IED控制、监视和/或保护的主电力系统对象接收的数据，人机界面(HMI)15可以与IED包括在一起。HMI可以操作地连接到CPU、逻辑和信号处理模块。HMI也可以包括允许用户输入的元件以控制主电力系统对象。HMI可以包括一个或多个显示器，用来同时或顺序地显示详细信息和/或允许控制多个主电力系统对象的多个页面。这些其本质上且自动的表现出新颖性且不为现有技术所知。
【0028】IED可以包括存储器17，用于暂时地和/或永久地存储关于所监视、保护和/或控制的主电力系统对象的信息。存储器也可以存储关于从至少一个电力系统主对象接收的数据的分析信息。例如，存储器可以存储关于事件和/或干扰的信息，诸如导致检测到事件和/或干扰的对象的时间和参数。存储器模块的容量可以根据实施例和需求或所期望的功能而变化。存储器模块的一个实施例包括多达40个模拟通道和100个干扰的干扰记录。存储器可以操作地连接到信号处理、CPU和/或逻辑模块。
【0029】可以包括控制和监视通信模块19，以为中央控制和/或监视单元提供信息。控制和监视通信模块可以被操作地连接到信号处理、CPU和/或逻辑模块。
【0030】根据本发明的IED也可以包括时间同步模块。为了获得精确的时间基准，时间同步模块可以与全球定位系统(GPS)同步，以帮助确保基准时间是精确的。时间同步模块可以允许IED与其他IED和/或其他元件同步。时间可以用于记录电力系统中事件和干扰发生在何时，以及简单地掌握电力系统的运行。
【0031】电源模块操作地将IED连接到电源。
【0032】根据本发明的IED也可以包括用于模拟电流信号的电流输入模块。电流输入模块中的通道的数目可以变化。一个特定实施例包括6个通道。输入模块的精确度可以变化。根据一个实施例，输入模块具有大约0.1％的精确度。
【0033】而且，根据本发明的IED可以包括光学以太网模块。以太网连接是控制和监视通信和/或远程保护通信的实际实现的一个示例。在后面的情况中，其可以是另一个IED或与保护任务有关的任一其他处理设备。
【0034】根据本发明的IED可以被配置成适合电力系统中的不同保护方案和体系结构。如上所述，IED可以监视、控制和/或保护多个设备。根据本发明的IED可以连接的电力系统元件的示例包括：
具有一个或多个断路器的传输线和电缆；
具有多达六个输入的两绕组和三绕组电力变压器；
具有多达六个输入的多终端线；
包括线和变换器、发电机、变换器块的复合对象；或
多底板(multi bay)应用，包括一个串的(one diameter)断路器和半个串的站或H站(H-station)。
【0035】图2-6示例说明连接到电力系统元件的IED的具体示例，并且同样，在一些例子中，示出关于这些应用的现有技术解决方案的示例。图2代表控制双断路器的IED的实施例的示意图。图3a和图3b分别示出用于保护、控制和监视六个馈电线的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图。在图3a和3b中，仅示出了第一和第六馈电线。图4a和4b分别示出用于保护、控制和监视两个干线的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图。图5a和5b分别示出用于冗余地保护、控制和监视两个干线的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图。图6a和6b分别示出用于保护、控制和监视多个不同电力系统对象的根据现有技术的解决方案和根据本发明的解决方案的实施例的示意图。
【0036】如在这些解决方案中看到的，本发明可以大大地减少监视、控制和/或保护电力系统元件所必需的硬件的数量。本发明也可以在系统中提供冗余。例如，在图5b所示的实施例中，每个IED可以在不同干线中保护线路中的一条，使得如果一个IED失效，IED仍保护两个线路。
【0037】在本说明书中示出和讨论的实施例仅旨在向本领域技术人员教导发明人知道的制造和使用本发明的最佳方式。在本说明书中，任何内容都不应当被看作对本发明的保护范围进行限制。示出的所有示例是代表性和非限制性的。根据上述教导，本领域技术人员应理解，在不脱离本发明的情况下，可以修改或改变本发明的上述实施例。因此应当理解，在权利要求和它们等价的范围内，可以以不同于所具体描述的方式实现本发明。
