Description
技术领域technical field
本实用新型属于数字化变电站域监控设备领域，尤其是一种用于数字化变电站的站域测控装置。The utility model belongs to the field of digital substation domain monitoring equipment, in particular to a station domain measurement and control device for digital substations.
背景技术Background technique
变电站自动化系统经历了从集中到分散过程。在变电站自动化集中式是指使用RTU的时代。当时使用远方数据终端(RTU)负责全站四遥信息的采集。但是因受装置处理能力的限制，单个RTU采集信息有限，已经远远不能满足后台对全站信息的需求。因此变电站自动化开始走向分散式，按间隔配置采集单元。随着光电传感技术的发展以及IEC61850技术标准的建立，数字化智能变电站在变电站中扮演着越来越重要的角色。在智能变电站中，采样数据的共享以及以太网网络模式，使得一台测控接入多个间隔成为可能，减少了设备，有利与运行于管理。从经济角度看，现在对变电站占地面积的要求越来越高。因此从长远来看，变电站自动化系统的再次集中已经不可避免。Substation automation system has gone through the process from centralized to decentralized. Centralization in substation automation refers to the era of using RTU. At that time, the remote data terminal (RTU) was used to collect the four remote information of the whole station. However, due to the limitation of the device's processing capacity, the information collected by a single RTU is limited, which is far from meeting the needs of the background for the information of the whole station. Therefore, substation automation begins to move towards decentralized, and the acquisition units are configured at intervals. With the development of photoelectric sensing technology and the establishment of IEC61850 technical standards, digital smart substations are playing an increasingly important role in substations. In the smart substation, the sharing of sampling data and the Ethernet network mode make it possible for one measurement and control unit to access multiple intervals, which reduces equipment and is beneficial to operation and management. From an economic point of view, the requirements for the area occupied by substations are getting higher and higher. Therefore, in the long run, the re-centralization of the substation automation system is inevitable.
国内外对集中式测量装置的研究要么停留在功能单一的RTU时代。要么是对几个间隔的少量集成。如针对3/2接线的一个串的测控装置，或针对整个变压器的变电压器测控装置，这些测控装置虽然做了一些集中测量的功能，但是集中测量的间隔数很少，对整个电压等级所有间隔或整个变电站的集中式测量，远远达不到站域测控测量要求。The research on centralized measuring devices at home and abroad or stay in the era of RTU with a single function. Either a small number of integrations over a few intervals. For example, the measurement and control device for a string of 3/2 wiring, or the transformer measurement and control device for the entire transformer. Although these measurement and control devices have some centralized measurement functions, the number of intervals for centralized measurement is very small. The centralized measurement of intervals or the entire substation is far from meeting the requirements of station domain measurement and control measurement.
