Loose coupling architecture multi-station fusion monitoring system based on virtual machine

Abstract

The invention relates to a loose coupling architecture multi-station fusion monitoring system based on a virtual machine. The system is characterized in that a region I comprises a transformer substation module and an energy storage station module; the transformer substation module is provided with three layers and two networks; the energy storage station module is provided with a monitoring control network, and the monitoring control network is provided with sub-networks according to battery pack partitions and is cascaded to a station control layer network through a convergence switch; a region II is used for transmitting equipment online monitoring related information in the transformer substation module and environment, security and fire protection information of each functional modulesubarea of the whole substation; and a region IV is used for transmitting video monitoring image information of each functional module area of the whole substation. On the basis of an integrated monitoring platform, decoupling of a station level application function and hardware server equipment and online migration of the station level application function and the hardware server equipment on different servers of the hardware layer equipment are realized in a mode of creating a virtual machine, so that the software and hardware chimney erection phenomenon and the software and hardware compatibility problem among different manufacturers are avoided, and the hardware application efficiency and the system reliability are improved.

Problems solved by technology

[0005] (1) The software and hardware are tightly coupled. As the related functions of the station control layer increase, the number of hardware increases linearly, and the cost and operation and maintenance workload increase accordingly, which is not conducive to system expansion

The current monitoring system software and hardware basically have a one-to-one relationship, that is, a single or multiple fixed software is installed on a fixed server to achieve fixed functions. The corresponding relationship between software and hardware is clear and fixed. The model is simple and clear, but for multi-station fusion substations, when the software function requirements of the station control layer increase, the corresponding hardware also increases almost linearly, resulting in a significant increase in cost and operation and maintenance workload

[0006] (2) There is a chimney-like relationship among the various subsystems, and there is no effective integration, which is not conducive to the integrated display of information, making it difficult to screen information and increase the difficulty of operation and maintenance

The multi-station fusion station monitoring system not only includes the substation's original monitoring, metering, credit guarantee, wave recording, PMU, online monitoring, intelligent auxiliary control, fire protection and other subsystems, but also includes the battery information monitoring and energy management system of the energy storage station , as well as the information monitoring subsystems of security, fire protection and environment in building areas such as energy storage and data centers, the number of systems and the amount of information data have increased significantly. If the traditional model is still adopted, the hosts between subsystems are independent, and information is relatively isolated. Systems and scattered information cause operation and maintenance personnel to move between different systems, artificially analyze the correlation between information, and the workload of operation and maintenance is huge

[0007] (3) The systems of different manufacturers are difficult to be compatible, and it is impossible to take advantage of multiple companies, and it is difficult to upgrade and transform the equipment of the same manufacturer

The existing monitoring system solutions generally provide an integrated monitoring system platform by the monitoring system manufacturer, and simultaneously provide a series of functional software in the background. The software provider is single, and it is difficult to integrate the strengths of each company to optimize the background function configuration of the station control layer.
