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. 　　数字化站保校相变变变变变变变变变变变,在站运行的条件下部分隔保校的度很大变变变变变变变变变变变变变变变变变变变变变变变,目前的常保变变变变 变变变变变变变变变变变变变变变变变变变变变变变校装置无法提供数字化保所需的流量和量,因流量和量必合并器变变变变变变变变变变变变变变变 才能入保装置变变变变变变,而要完成必自合并器提供模中的流量和量变变变变变变变变变变变变变变变变变变变变变变变变,要完成母差保变变变 需要大量流量的保校便得尤变变变变变变变变变变变变变变变变变变困。 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通信本身并变变变变变变变变变变变变变变变变变变变变变变变未站网系的安全性做任何定,同本身的放性变变变变变变变变变 和准性站的网安全来重大变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变变患。要做到二次系信息的保密性、完整性、可用性和确定性, 符合二次系安全防的要变变变变变变变变求,是自化厂家变变变变变变变变变变变变变变变变变变变变仍需考和完善的技。然目 前已投运的站采取了防变变变变变变变变变变变变变变变变变变变变变变变火、分分区隔离等手段行防,但防的变变变变变变变变变变变变变效果仍有待的考。 IEC61850 communication protocol does not itself to the network security system for substation to make any provisions, at the same time to the network security of substation major hidden trouble of openness and standardization of the protocol itself. To do two times the system information confidentiality, 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、数字化站的变变变变变变变变未来展 4, the future development of digital substation 　　数字化站技的展将是个期的程变变变变变变变变变变变变变变变变,需要考变变变变变变变变变变变变变变变变与目前常站技的兼容性。(1)变变变程常 变变变变变变变变变变变变变变变变变变变变变变接入。程常主要指互感器和断路器,具体用变变变变变变变变变变变变就是采取非常互感器 技和智能断路器技变变变变变变变变变,或智能断路器控制器技变,常的接人方式主要有变变变变变变变变变变变3变基本模式:常互感器变变变变 和常断路器变变变变;常互感器和智能断路器变变变变变变变变变变;非常互感器和常断路器。变变变变变变变变变变变(2)变变变变变变变变变变变变程方案。在第二段中,前 面控制和量数据的分离通信系将合并到一变变变变变变变变变变变变变变变变变起,控制和量数据的合并变变变变变变变变变变变变变变变变变变减少了隔接的性,但变变变隔 IED变变变变变变变变变变变变变变变变变变变变变变变变变变变需要两个以太网口分与程和站接。由于送了来自合并 元的数字化气量系的变变变变变变变变变变瞬,此变变变变变变变变变变变变变变变变变变变变变变变变变变变变通信方式比第一段中的通信方式更快。出于个原因将使用100 Mbit/s以太网,通程保装置的变变变变变变变变变变变变变变变变变变变变变变跳命令被送到断路器。(3)变变变变变变变变变变变程和站合并方案。 由于第一,第二段中程和站都变变变变变变变变变变变变变变变变变变变使用了基于MMS变变变变变变变变变变用通信堆的以太网,和以太网的不 断展变变,使得接构成一个通信网变变变变变变变变变变变变变,并且不会影响变变变变变变变变变变站内部站的通信。 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 transmission 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.　　变变 Conclusion 　　数字化站合自化系的变变变变变变变变变变变变变,推变变变变变变变变变变变变变变变变变变变变展。数字化了网自化技的一步 站技展程中可以常站技的变变变变变变变变变变变变变变变变变变变变变兼容,变变变变变变变变变变变变变意味着数字化站用技的展可以 建立在有站自化技的基上用上的变变变变变变变变变变变变变变变变变变变变变变变变变变变变突破步平展和逐,使新技的用能有机地变变变变变变变变变 合网的展变变变变变,未来在数字化站用技成变变变变变变变变变变变变变变变变变变变变变变变变变变变变变熟的基上将志着新一代数字化网的。 Realization of digital substation integrated automation system, promoting the further development of power system automation technology.
