Description

Intelligent recorder master station management method and system based on transparent system architecture
Technical Field
The invention relates to the field of relay protection, in particular to an intelligent recorder master station management method and system based on a transparent system architecture.
Background
The intelligent substation is an important fulcrum for intelligent power grid construction, and the operation reliability of the intelligent substation is related to the stability of the whole power grid. The original monitoring equipment has small monitoring surface, non-uniform data format, rough alarm information, complete dependence on manual arrangement and analysis, large workload and low efficiency. Therefore, in 2018, the power industry provides a new generation of four-in-one intelligent recorder, integrates new functions such as protection action analysis, secondary system visualization, equipment operation and maintenance on the basis of the original fault wave recording function, and can comprehensively reflect the operation conditions of a primary power transmission and transformation system, a secondary relay protection system, network equipment, network messages and the like of a transformer substation.
At present, a new generation of intelligent recorder is in a test point stage, and no intelligent master station system matched with the new generation of intelligent recorder exists, so that the traditional master station system for recording waves is still used. The traditional master station only has the functions of calling and analyzing the fault wave recording files, and is not supported for the newly added functions of protection action analysis, secondary system visualization, equipment operation and maintenance and the like. Therefore, the application range of the new-generation intelligent recorder is limited to the transformer substation, and the intelligent recorder cannot be extended to the power grid dispatching level, so that the intelligent recorder is not beneficial to effective utilization and popularization.
At present, there are two main types of master station systems for managing a recorder: the first is a signal-protecting master station and the second is a wave-recording master station. The information-protection main station mainly depends on the information-protection sub-station at the substation end, and because the management equipment is more, the information to be collected is complex, the reliability of the system is low, the problems of low uploading success rate, long time consumption, no fault analysis function and the like exist, and the operation effect is not ideal, the mode of independently constructing the wave-recording main station is adopted at present. The existing wave recording master station systems are limited by the operation characteristics of wave recorders, and mainly have the following defects:
1) The information is opaque, the centralized management and control difficulty is high, and the construction cost of the main station is high.
At the transition stage of the intelligent substation of the current conventional substation item, IEC103, IEC61850 and private protocols coexist, and in addition, the same type of communication protocols of all factories are different. In order to realize one-stop compatible access, a huge system model needs to be established according to the information technology architecture of the existing master station system, and the workload is huge and the reliability is low, so that the problems that a plurality of stock devices cannot be accessed and the incremental device joint debugging period is long still exist.
2) The data is opaque, the analysis and diagnosis means are not enough, and the accident handling flow is complex.
Because of lack of standardization requirements, the wave recording files generated by wave recorders of various manufacturers have differences in file format, sampling frequency, channel definition, naming mode and the like, only uniform opening of the wave files can be realized, and as for fault analysis, the fault analysis mostly depends on manual analysis of a plant station side device or a dispatching side, the data utilization rate is low, and the automation level is insufficient.
3) The calculation is opaque, the system energy consumption is high, the large-scale data processing speed is low, and the efficiency is low.
The large information volume and concentrated burst of wave recording data under the rapidly expanding power grid scale become industry problems, and the traditional multi-machine collaborative scheduling architecture and the multi-thread task processing mechanism have difficulty in coping with the increasing processing demands of mass data. Because of the opacity of the system resource allocation and task coordination mechanism, the CPU load rate of the master station system is high, the load rate is maintained above 25% for a long time under the normal running condition, the load rate exceeds 50% under the big data processing condition, and the conditions of blocking and downtime occur, but the cost is greatly improved but the effect is very little by improving the equipment configuration and increasing the equipment quantity.
4) The operation is opaque, the reliability of the system is poor, the maintenance workload is large, and the labor cost is high.
The system has low reliability, high coupling performance to factors such as models, environments, configuration and the like, and is easy to fail in data uploading or analysis due to reasons such as inconsistent models, severe network environments, configuration errors, file deletion and the like. Meanwhile, the evaluation and early warning mechanism for the target and the self running situation is imperfect, the fault analysis and the troubleshooting depend on manual work, and the daily maintenance workload is great.
With the improvement of the complexity of the power grid environment, the effectiveness of relying on artificial experience and cognition is greatly reduced, the main reason is that the running state of the power grid is 'opaque', the power grid fault information perceived by a dispatcher is not timely and comprehensive, when the power grid is abnormal or has faults, massive and multi-point data are concentrated and burst-type to rise, the dispatcher is very easy to generate cognition disorder under the interference of large information quantity, the judgment is reduced, and accurate analysis and decision making are difficult to be made in a short time, and only experience judgment can be relied on. However, the power grid fault analysis needs a comprehensive work with multiple professions, disciplines and multiple systems, even a dispatcher with abundant experience can hardly ensure timely and accurate scientific decision making, so that the accident handling efficiency is low, the power failure time is prolonged, and even a secondary accident caused by equipment damage due to decision errors is easy to occur.
Furthermore, grid technology iterations are also accelerating. The new generation intelligent recorder has more huge information quantity, more complex network structure and message type, and sets higher professional 'threshold' for the modulator, but provides more multi-angle power grid operation information at the same time. Therefore, a scheduler needs a more intelligent recorder master station to fully consume and use this information, providing more powerful decision support.
In the context of a computer system architecture, "transparency" means that the underlying algorithms or instructions of the computer system may be used by a developer without the developer needing to operate their principles, i.e., present but not to be understood. Similarly, the complex message data and the transmission process thereof in the intelligent substation are not required to be known by the dispatcher, and only the power grid state reflected by the message is required to be displayed to the dispatcher after being processed.
In the operation of the power grid, the transparent power grid provided by the Chinese engineering institute Li Li institute is a visible, known and controllable power grid which is realized by combining the modern information technologies such as computer technology, data communication technology, sensor technology, artificial intelligence and the like with the power grid. The new generation of 'four-in-one' intelligent recorder is a powerful sensor, but the application technology of the intelligent recorder is lacking at a dispatching end, so that the design of a main station is supported by using the data base of the intelligent recorder to visualize the running state, sense the fault depth and control the power grid.
To summarize, no commonly applicable method exists at present, and the problem that the master station management of a recorder is not intelligent enough and transparent can be solved.
