The invention belongs to the field of power systems, and particularly relates to a remote retrieval-based SCADA operation method for integration of a main network and a distribution network.
Background
Most of domestic urban power distribution automation systems adopt an independent construction and independent operation mode with a dispatching automation system, distribution network information inside and outside a transformer substation respectively accesses the dispatching system according to voltage grades in the distribution mode, then a model inside the transformer substation is exported from the local dispatching system and imported into the dispatching system to realize synchronization, and distribution network regulators and automation personnel need to use and maintain and dispatch two sets of system graphs and data at the same time. With the expansion of the coverage range of distribution automation and the continuous deepening of the application, the mode has more defects in the aspects of scheduling application, data storage, model correspondence, topology analysis and the like, and cannot adapt to the characteristic of frequent change of a distribution network graph model, the information interaction between systems is still in a static data forwarding mode at the level of monitoring and data acquisition (SCADA), and the problems of data redundancy, difficult information synchronization, easy inconsistency and the like exist, the existing data interaction mode which is mainly planned cannot meet the requirements of information sharing and interaction between systems and the cooperative operation of advanced applications, the contradiction to the integral operation control requirement of the intelligent distribution network is increasingly prominent, the intelligent distribution network construction and management requirements cannot be better met, and the investment benefit of the distribution automation construction cannot be effectively played.

FIG. 1 is a schematic flow chart of an embodiment of the present invention.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
In this embodiment, the DMS and EMS are both systems for computer monitoring, control, and auxiliary management of the power system for safe, economical, and high-quality operation services, and require a large amount of data acquisition, transmission, and processing (including static data, real-time data, and quasi-real-time data). The development of the SCADA system and the SCADA system is established on the basis of SCADA, and the SCADA system are continuously developed towards the directions of opening and integrating along with the development of power systems and computer technologies.
As shown in fig. 1, in the master and distribution integrated SCADA operation method based on remote review in this embodiment, the master and distribution networks are located in different domains (DMS is located in the distribution network, EMS is located in the master network), each user is granted different permissions, and the user with the corresponding permission can perform the corresponding operation.
The operation method of the embodiment comprises the following steps:
1) the method comprises the steps of performing cross-domain real-time library access on a main network and a distribution network, wherein the current real-time library accesses real-time library content in another domain in a cross-domain mode, namely inputting a remote system name needing to be accessed in another domain by a client of the current domain, then sending an access request to a corresponding remote system through a proxy server, and finally returning a result to the client of the current domain for display after the remote system processes the access request, so that the information of the main network and the distribution network is integrally displayed.
For example, when the EMS system views the prompt information of the device in the DMS system in a remote access manner, the EMS system needs to access the device in the DMS system through a cross-domain real-time library to query and display the information of the device in the DMS system. In the process, whether the device belongs to the local domain needs to be judged, and if not, a cross-domain access mode needs to be set to access the DMS system.
2) Performing cross-domain authority management on the main network and the distribution network, and judging whether the user has the authority of the operation in another domain according to the user logged in the domain so as to allow or reject the corresponding operation of the user, thereby realizing cross-domain authority control on the SCADA operation;
the authority comprises five types of authority main bodies including functions, roles, users, groups and special attributes, wherein: the function is the smallest non-separable unit of authority in cross-domain authority management; the roles comprise a system administrator, a security administrator, an audit administrator and an application administrator; the groups correspond to different functional departments; the user corresponds to a specific worker; the special attribute is a special definition of a specific authority object, and can be endowed with a user or a role and used together with functions to realize different authority control functions.
For example, in the EMS system, the devices in the DMS system are counted in a remote manner, and it is necessary to determine whether the currently logged-in user has a counting right in the DMS system in a cross-domain right management manner, and if yes, the user passes the counting right, and if not, the user rejects the counting right. In the process, whether the device belongs to the local domain needs to be judged, if not, cross-domain authority management needs to be set, and the authority is verified.
3) And a cross-domain message bus is established in the automation systems of the main network and the distribution network and among different systems, when equipment of another domain is operated in the domain, the domain sends messages in the mode of messages in the other domain, and the other domain receives the messages in an undifferentiated mode, so that cross-domain mutual transmission of the messages is realized.
For example, if a device in the EMS system is blocked by remote access in the DMS, then the EMS device blocking message needs to be sent from the DMS to the EMS in a cross-domain message and processed by the EMS. In the process, whether the message is cross-domain or not is not required to be specially set, and the cross-domain message bus provides cross-domain mutual transmission of the message, so that the main and distribution network messages can be mutually transmitted in the system.
The cross-domain message bus can adopt two modes: one is to adopt a centerless structure, each node is completely equivalent and has a message forwarding function; all the nodes are connected with each other pairwise and directly carry out message delivery. The other is to adopt a central structure, all nodes communicate through a central server, and the central server plays a role in caching and distributing messages in the middle.
In the embodiment, firstly, cross-domain real-time library access is performed under a main distribution integration system architecture based on remote retrieval, so that the main distribution integration information display function is realized; secondly, performing cross-domain authority management based on a main distribution integrated system architecture of remote retrieval to realize authority control on SCADA operation; thirdly, through a cross-domain message mechanism based on remote retrieval, cross-domain mutual transmission of messages is realized, functions of Tip display, parameter retrieval, remote signaling and remote measuring number blocking, alarm suppression, curve query, signboard operation and the like on the basis of remote retrieval are finally realized, and the functions jointly form an SCADA operation method on the basis of remote retrieval.
The embodiment can be further modified as follows: a) historical data in another domain is accessed indifferently in the current domain. b) After the device in the other domain is operated in the current domain, the other domain updates and feeds back the device information in real time.
The present invention is not limited to the above embodiments, and the technical solutions of the above embodiments of the present invention may be combined with each other in a crossing manner to form a new technical solution, and all technical solutions formed by adopting equivalent substitutions fall within the protection scope of the present invention.
