3、数字化变电站应用中存在的问题
There are 3 problems in application, digital substation
由于光电/电子式互感器本身的结构特点和工作方式,导致互感器的角差、比差现场试验
难以进行,甚至极性试验也无法开展,只能等到设备投运带电后,才能检验接线的准确性。另外,
光电/电子式互感器的局放试验、伏安特性试验的试验方法和标准也与常规设备有很大的区
别,这都需要设备厂家和运行主管单位专门制定。
Because the optical / electronic transformer \'s structure characteristics and working way, resulting
in transformer angle difference, difference field test is difficult to carry out, even polarity test can
not be carried out, can only wait until the equipment commissioning charged, connection to test
accuracy. In addition, test methods and standards of electronic transformer photoelectric /
discharge test, voltage-current characteristic test also has the very big difference with the
conventional devices, which require equipment manufacturers and operating units in charge of
special formulation.
数字化变电站保护校验相对复杂,在变电站运行的条件下对部分间隔保护校验的难度很
大,目前的常规继电保护校验装置无法提供数字化保护所需的电流量和电压量,因为电流量和
电压量必须经过合并器才能进入保护装置,而要完成试验必须自带合并器提供模拟试验中的
电流量和电压量,要完成母差保护这类需要大量电流电压量的保护校验便显得尤为困难。
Digital substation protection check is relatively complex, in the substation operation conditions on
some interval checking protection is very difficult, the conventional verification of relay
protection device is unable to provide the amount of current and voltage digital protection required,
because the amount of current and voltage must be combined to get to the protection device, and
to complete the test must bring their own merger provides current and voltage simulation test, to
complete the bus differential protection check this class needs a large number of current and
voltage is particularly difficult.
IEC61850通信协议本身并未对变电站网络系统的安全性做任何规定,同时协议本身的开
放性和标准性给变电站的网络安全带来重大隐患。要做到二次系统信息的保密性、完整性、
可用性和确定性,符合二次系统安全防护的要求,是自动化厂家仍需考虑和完善的技术环节。
虽然目前已投运的变电站采取了防火墙、分层分区隔离等手段进行防护,但防护的效果仍有

/ /
待时间的考验。
IEC61850 communication protocol does not itself to the network security system for substation to
make any provisions, at the same time t苏轼水调歌头全文 o the network security of substation major hidden trouble
of openness and standardization of the protocol itself. To do two times the system information
confidentiali南望王师又一年全诗 ty, integrity, availability and deterministic, in line with the two system security
protection requirements, is the automation manufacturers still need to consider and perfect
technical links. Although the substation has been put into operation to take firewall, hierarchical
partition and other means of protection, but the protective effect remains to be the test of time.
4、数字化变电站的未来发展
4, the future development of digital substation
数字化变电站技术的发展将是个长期的过程,需要考虑与目前常规变电站技术的兼容
性。(1)过程层常规设备接入方案。过程层常规设备主要指互感器和断路器设备,具体应用就
是采取非常规互感器技术和智能断路器技术,或智能断路器控制器技术,常规设备的接人方式
主要有3种基本模式:常规互感器和常规断路器;常规互感器和智能断路器;非常规互感器和
常规断路器。(2)过程总线方案。在第二阶段中,前面控制和测量数据的分离通信系统将合并
到一起,控制和测量数据的合并减少了间隔接线的复杂性,但间隔层IED设备需要两个以太网
口分别与过程总线和变电站总线连接。由于传送了来自合并单元的数字化电气量测系统的瞬
时值,此种通信方式比第一阶段中的通信方式更快。出于这个原因将使用100 Mbit/s以太网,
通过过程总线保护装置的跳闸命令被发送到断路器。(3)过程总线和站总线合并方案。由于
第一,第二阶段中过程总线和变电站总线都使用了基于MMS应用层通信堆栈的以太网,和以
太网的不断发展,使得变电总线联接构成一个通信网,并且不会影响变电站内部站的通信。
Development of digital substation technology will be a long-term process, need to consider and
conventional substation technology compatibility. ( 1 ) the process layer of conventional
equipment access scheme. Process of conventional equipment mainly refers to the transformer and
the circuit breaker, the specific application is to take unconventional transformer technology and
intelligent circuit breaker technology, or intelligent circuit breaker controller technology,
conventional equipment access way mainly has 3 kinds of basic models: conventional transformer
and conventional circuit breaker; routine transformer and intelligent circuit breaker; non
conventional instrument transformer and conventional circuit breaker. ( 2 ) the process bus scheme.
In the second stage, separation of communication system in front of control and measurement data

/ /
will be combined together, merger control and measurement data reduces the complexity of
interval connection, but the interlayer IED devices require two Ethernet ports which are
respectively connected with substation process bus and bus. Because the instantaneous
tra对酒当歌强乐还无味 nsmission digital electric quantity from the merging unit test system, the communication mode
is faster than the first stage of communication. Will use the 100 Mbit/s Ethernet for this reason,
through the process of bus protection trip command is sent to the circuit breaker. ( 3 ) for process
bus and station bus merging scheme. Since the first, second stage process of bus and substation
bus using the MMS application layer communication stack based on Ethernet, continuous
development and Ethernet, the substation bus connected to form a communication network, and
will not affect the communication within the substation station.
