应用于智能电网的电力小无线专网系统Electric small wireless private network system applied to smart grid

技术领域:Technical field:

本发明涉及一种应用于智能电网的电力小无线专网系统。The invention relates to a power small wireless private network system applied to a smart grid.

背景技术:Background technique:

随着智能电网建设的深入,越来越多的智能化设备需要接入到智能电网的综合调度系统中,国家电网公司坚强智能电网建设的总体要求,是保证智能电网建设规范有序推进,实现电力用户用电信息采集系统建设“全覆盖、全采集、全预付费”。特别是随着智能电网的营销、配网、调度系统的一体化平台系统的建设深入,关于营配调各个系统内的终端和通信系统在速率、可靠性、实时性、兼容性上提出了较高的要求。With the deepening of smart grid construction, more and more intelligent devices need to be connected to the integrated dispatching system of the smart grid. The construction of the electricity consumption information collection system of power users is "full coverage, full collection, and full prepayment". Especially with the deepening of the construction of the integrated platform system of the marketing, distribution network, and dispatching system of the smart grid, relatively high-speed, reliability, real-time, and compatibility proposals have been made for the terminals and communication systems in each system of marketing, distribution, and dispatching. high demands.

智能电网通信系统目前主要由光纤通信系统、载波通信系统和无线通信系统三种通信方式组成,其中无线通信方式主要是指由GPRS和3G等无线公网组成的无线通信方式,并且目前此种通信方式已经大规模的运用到营销系统的集抄和部分一遥、二遥的配电终端系统中。The smart grid communication system is currently mainly composed of three communication modes: optical fiber communication system, carrier communication system and wireless communication system. The wireless communication mode mainly refers to the wireless communication mode composed of wireless public networks such as GPRS and 3G. The method has been widely used in the centralized copying of the marketing system and some one-remote and two-remote power distribution terminal systems.

现有的无线公网通信系统中,存在计费费用较高、无线信号覆盖不全面等多种不足的问题。同样,在光纤通信系统中,存在施工铺设成本费用较高等问题,在某些特定的区域,并不是最适合的大规模铺设组网的通信系统解决方案。另外,在配网通信系统中,往往设备铺设与10KV的中压系统侧,对设备的低压取电是一个比较棘手的系统解决方案。In the existing wireless public network communication system, there are various deficiencies such as high billing fees and incomplete wireless signal coverage. Similarly, in the optical fiber communication system, there are problems such as high construction and laying costs, and in some specific areas, it is not the most suitable communication system solution for large-scale laying and networking. In addition, in the distribution network communication system, equipment laying and 10KV medium-voltage system side are often involved, and low-voltage power supply for equipment is a tricky system solution.

面对上述智能电网中的较棘手的技术问题,采用微功率无线系统作为智能电网系统中的特定区域的通信解决方案较为合适,主要解决智能电网系统中的以下几个问题:In the face of the above-mentioned difficult technical problems in the smart grid, it is more appropriate to use the micro-power wireless system as a communication solution for a specific area in the smart grid system, mainly to solve the following problems in the smart grid system:

铺设成本与难度问题:在智能电网通信系统中,通信线路的铺设一直是一个较难解决的施工难题,小功率无线系统采用短距离的功率放大,可以实现通信系统的区域覆盖,在一个区域内采用无线通信方式,不需要铺设通信线路。Laying cost and difficulty: In the smart grid communication system, the laying of communication lines has always been a difficult construction problem to solve. The low-power wireless system uses short-distance power amplification to achieve regional coverage of the communication system. Using wireless communication, no need to lay communication lines.

无线公网不能全覆盖问题:无线公网借用电信运营商的无线公共网络,在偏远区域,部分封闭空间,无线公网覆盖度不全,导致众多用户和配电数据不能及时上传。采用微功率无线通信系统,构建区域无线专网,保障区域内的无线数据及时有效传输。The wireless public network cannot fully cover the problem: The wireless public network borrows the wireless public network of the telecom operator. In remote areas, some closed spaces, the coverage of the wireless public network is not complete, resulting in the inability to upload many users and power distribution data in time. A micro-power wireless communication system is used to build a regional wireless private network to ensure timely and effective transmission of wireless data within the region.

无线通信可靠性不高的问题:由于采用无线公网的通信系统,由于共用电信数据传输网络,较为容易的被大量无关用户捕获或干扰,存在较大的安全隐患。采用微功率无线通信方式,系统内部集成安全加密和安全冗余系统,可以从物理层和网络层保障数据的通信安全和可靠。The problem of low reliability of wireless communication: due to the use of the wireless public network communication system, due to the shared telecommunications data transmission network, it is relatively easy to be captured or interfered by a large number of irrelevant users, and there is a large security risk. Using micro-power wireless communication, the system integrates security encryption and security redundancy system, which can ensure the security and reliability of data communication from the physical layer and network layer.

配网系统中低压取电问题:在偏远的10KV配网区域,通信设备和终端设备的取电问题一直是困扰系统推广的较大的技术难题。采用低功耗的无线通信系统,通过降低功耗和主动休眠的方式,可以使得设备的功耗在mw级,部分现场采用电池供电模式都可以维持较长时间的设备运营。The problem of low-voltage power supply in the distribution network system: In the remote 10KV distribution network area, the problem of power supply for communication equipment and terminal equipment has always been a major technical problem that plagues the promotion of the system. Using a low-power wireless communication system, by reducing power consumption and active sleep, the power consumption of the device can be reduced to the mw level, and some sites can maintain long-term device operation with battery power supply mode.

综上所述,采用低功率无线的通信方式构建的区域电力通信专网可以有效的弥补智能电网通信系统中的难以解决的系统难题,为智能电网的通信系统构建提供一种较新的通信方式。In summary, the regional power communication private network constructed by low-power wireless communication can effectively make up for the difficult system problems in the smart grid communication system, and provide a relatively new communication method for the construction of the smart grid communication system .

与已有技术相比,本发明的有益效果体现在:Compared with the prior art, the beneficial effects of the present invention are reflected in:

国家电网公司坚强智能电网建设的总体要求,是保证智能电网建设规范有序推进,实现电力用户用电信息采集系统建设“全覆盖、全采集、全预付费”。低压居民户表抄读覆盖范围最广,用户量最大,是目标实现的重点。The overall requirement of the State Grid Corporation of China for the construction of a strong smart grid is to ensure that the construction of the smart grid is promoted in an orderly manner, and to achieve "full coverage, full collection, and full prepayment" in the construction of a power user information collection system. Low-voltage residential meter reading has the widest coverage and the largest number of users, and is the focus of goal realization.

低压抄表系统按照抄表通信方式分有两类:有线和无线。有线抄表方式主要使用RS-485总线和低压载波抄表系统;无线抄表应用主要为GPRS无线公网通信模块。并且在目前的低压抄表系统中,采用采集器与集中器相互结合的通信方式,往往是采用两种通信方式混合的通信模型:采集器与集中器之间采用低压载波通信方式,集中器与集抄服务器之间采用GPRS通信方式。There are two types of low-voltage meter reading systems according to the meter reading communication methods: wired and wireless. The wired meter reading method mainly uses the RS-485 bus and the low-voltage carrier meter reading system; the wireless meter reading application mainly uses the GPRS wireless public network communication module. Moreover, in the current low-voltage meter reading system, the communication mode combining the collector and the concentrator is often adopted, which is a communication model in which two communication modes are mixed: the collector and the concentrator adopt a low-voltage carrier communication mode, and the concentrator and the concentrator The GPRS communication method is adopted between the centralized copying servers.

但是目前低压集抄系统还存在众多不足:低压配电网环境复杂,干扰大,低压电力线载波难以保证其抄表的稳定性;对于多台变供电的用电环境,由于载波串扰,不宜实施载波抄表方案;由于载波传输距离有限,需要通过中继方式保证抄表覆盖范围,对于农村、城乡结合部等低密度住宅不能做到全覆盖,实施难度很大;低压电力线窄带载波速率低,实时性差,无法满足远程预付费,远程拉合闸的需求。However, there are still many shortcomings in the current low-voltage centralized reading system: the environment of the low-voltage distribution network is complex, the interference is large, and the low-voltage power line carrier is difficult to ensure the stability of its meter reading; for the power environment of multiple transformers, due to carrier crosstalk, it is not suitable to implement carrier Meter reading solution; due to the limited transmission distance of the carrier, it is necessary to ensure the coverage of meter reading through relays, which cannot achieve full coverage for low-density residential areas such as rural areas and urban-rural fringes, and it is very difficult to implement; the low-voltage power line narrow-band carrier rate is low, real-time The performance is poor, and it cannot meet the needs of remote prepayment and remote opening and closing.

微功率无线通信技术可以克服其他通信方式在某些抄表应用场合的不足,施工方便,不需要额外铺设电缆,一般工人都可以方便的进行安装;通信不受限于电网特性,可方便的对跨台区、复杂用电环境快速实施抄表方案:通信速率快,实时性高,方便实施远程预付费,远程拉合闸等应用。Micro-power wireless communication technology can overcome the shortcomings of other communication methods in some meter reading applications. Rapid implementation of meter reading solutions in cross-platform areas and complex power consumption environments: fast communication speed, high real-time performance, and convenient implementation of remote prepayment, remote switching and other applications.

在低压集抄的通信管理平台中,微功率无线通信系统将结合现有的光纤通信系统和无线公网GPRS通信系统,共同组建起智能的低压集抄系统的底层网络平台。In the communication management platform of low-voltage centralized copying, the micro-power wireless communication system will combine the existing optical fiber communication system and wireless public network GPRS communication system to jointly form the underlying network platform of the intelligent low-voltage centralized copying system.

电网的智能化程度越来越高,智能变电站系统的要求越来越高。智能变电站是采用先进、可靠、集成和环保的智能设备,以全站信息数字化、通信平台网络化、信息共享标准化为基本要求,自动完成信息采集、测量、控制、保护、计量和检测等基本功能,同时,具备支持电网实时自动控制、智能调节、在线分析决策和协同互动等高级功能的变电站。The degree of intelligence of the power grid is getting higher and higher, and the requirements for the smart substation system are getting higher and higher. Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. At the same time, it is a substation with advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction.

采用微功率无线网络覆盖每个智能变电站的设备管理区域,建设智能变电站内的设备无线局域网,实现智能变电站内部的安防、检测设备互联互通,可以实现变电站内部的信息最大程度共享。The micro-power wireless network is used to cover the equipment management area of each smart substation, and the equipment wireless local area network in the smart substation is constructed to realize the interconnection and intercommunication of security and detection equipment inside the smart substation, which can realize the maximum sharing of information inside the substation.

需要构建坚强的智能电网建设工作,一个重要的建设工作内容就是实现配网自动化。在10KV和35KV的中压电网中,对电网的运行状态实现自动检测、故障分析、有效隔离、快速恢复,保障用户用电的可靠性和安全性。但是随着配网自动化系统建设面的铺开,配网自动化的通信系统面临着现场情况复杂、设备层级多样、可靠性要求较高等特点,据此,配网自动化的通信系统建设方案也比较多样,有光纤通信系统、无线通信方式和中压载波通信方式等。It is necessary to build a strong smart grid construction work, and an important construction work content is to realize distribution network automation. In 10KV and 35KV medium-voltage power grids, automatic detection, fault analysis, effective isolation, and rapid recovery of the operating status of the power grid are realized to ensure the reliability and safety of power consumption for users. However, with the spread of distribution network automation system construction, the communication system of distribution network automation is faced with complex site conditions, diverse equipment levels, and high reliability requirements. Accordingly, the communication system construction scheme of distribution network automation is also more diverse. , There are optical fiber communication systems, wireless communication methods and medium voltage carrier communication methods.

在目前的配网自动化通信系统的建设方案中,光纤通信方式可靠性和安全性价高,适用于城市核心区和新区的配网通信系统建设方案,但是施工较为复杂,使用成本也比较高,并不适用于大规模的城郊配网、老城区配网和农网配网通信系统的建设。载波通信方式为比较成熟的通信方式,施工比较便捷,但是由于以一次网架为通信传输介质,易受电力电缆环境的干扰,存在一定的局限性。目前大规模采用的GPRS或3G的无线公网通信技术在配网自动化系统中也广泛采用,但是由于易受公网信号的干扰,并且安全性和可靠性不能达到配网系统的要求,目前只能适用于一遥、二遥的通信现场,实现现场设备状态的监控。In the current construction plan of the distribution network automation communication system, the reliability and safety of the optical fiber communication method are high, and it is suitable for the construction plan of the distribution network communication system in the urban core area and new district, but the construction is more complicated and the use cost is relatively high. It is not suitable for the construction of large-scale suburban distribution network, old city distribution network and rural distribution network communication system. The carrier communication method is a relatively mature communication method, and the construction is relatively convenient. However, since the primary network frame is used as the communication transmission medium, it is easily disturbed by the power cable environment, and there are certain limitations. At present, the GPRS or 3G wireless public network communication technology widely used in the distribution network automation system is also widely used in the distribution network automation system. However, due to the interference of public network signals, and the safety and reliability cannot meet the requirements of the distribution network system, only It can be applied to the communication site of one remote and two remote to realize the monitoring of the status of field equipment.

采用微功率无线通信系统作为配网自动化的通信方式,在配网自动化区域现场构建以基于微功率无线区域覆盖专网,从方案成本上、可靠性和安全性上都可以对光纤通信、无线公网通信和中压载波通信方式进行有效的补充。本系统中的微功率无线通信系统采用网络数据交换和应用数据抓发的两种数据转换模型可以满足与光纤、无线、载波等多种通信方式的兼容和互联互通;并且本系统中的微功率无线设计了基于网络路由的互备系统和基于上联接口的互备方式,可以抵抗微功率无线网络的单点或者多点失效,最大程度上保证了系统的可靠性和安全性。另外由于在中压配网系统中,低压取电方式一直未困扰配网自动化系统发展的难题,采用微功率无线通信系统,结合微功率无线系统的低功耗、触发唤醒模式,可以采用干电池供电就能保持相当长的一段时间的系统用电量。The micro-power wireless communication system is used as the communication method of distribution network automation, and the on-site construction of the distribution network automation area covers the private network based on the micro-power wireless area. Network communication and medium voltage carrier communication are effectively supplemented. The micro-power wireless communication system in this system adopts two data conversion models of network data exchange and application data capture to meet the compatibility and interconnection with various communication methods such as optical fiber, wireless, and carrier; and the micro-power in this system Wireless has designed a mutual backup system based on network routing and a mutual backup method based on uplink interfaces, which can resist single-point or multi-point failures of micro-power wireless networks, and ensure the reliability and security of the system to the greatest extent. In addition, in the medium-voltage distribution network system, the low-voltage power-taking method has not troubled the development of the distribution network automation system. The use of a micro-power wireless communication system, combined with the low power consumption and trigger wake-up mode of the micro-power wireless system, can be powered by dry batteries. The power consumption of the system can be maintained for a long period of time.
