Description

A power grid dispatching automation system based on virtualization technology

technical field

The invention belongs to the technical field of electric power automation, and in particular relates to a power grid dispatching automation system based on virtualization technology.

Background technique

Cloud computing is an emerging technical field. Its core feature is to dynamically manage various resources of thousands of computers through a collaborative mechanism, and distribute them to various applications on the upper layer according to needs, so that it can form a database for massive data. Storage, processing and serving capabilities. Virtualization technology is the basic key technology for building cloud computing. It can realize the unified scheduling and efficient utilization of heterogeneous physical resources, and realize the flexible deployment and transparency of hardware resources in the power grid dispatching automation system. As shown in Figure 1, the granularity of server virtualization technology abstraction is the entire computer. Server virtualization refers to virtualizing a physical computer system into one or more virtual computer systems. Each virtual computer system is referred to as a virtual machine for short, and it has its own virtual hardware, including virtual CPU, virtual memory, and virtual I/O devices, to provide an independent virtual machine execution environment.

After server virtualization, the operating environment of the application becomes a virtual machine, which has the characteristics of partitioning, isolation, and encapsulation. Running multiple operating systems on a physical machine can make full use of server resources. The virtual machine is encapsulated into a file that has nothing to do with the hardware configuration, and the virtual machine can be migrated through a simple file copy.

In order to meet the objective needs of UHV power grid operation and comprehensively improve the ability of dispatching agencies to control large power grids, the State Grid Corporation of China has organized the development and promotion of a wide-area panoramic distributed integrated power grid dispatching technical support system platform. The system adopts advanced software development technology and is characterized by standards, openness, reliability, safety and adaptability. It directly carries real-time monitoring and early warning (new EMS), dispatching plan (OPS), safety check (SCS) and dispatch Management (OMS) and other basic platforms for four categories of applications, the unified platform has laid the foundation for us to build an integrated power grid dispatching automation system with the help of virtualization technology. Because there are many types of applications, one application occupies one server, resulting in a large waste of resources. With the help of virtualization technology, servers can be unified and virtualized into resource pools, and corresponding servers can be customized according to specific application requirements.

At present, the power automation system hardware of the power dispatching center is composed of a large number of server clusters, including monitoring and control server groups, analysis and decision-making server groups, security check server groups, dispatch planning server groups, and dispatch management server groups. Each software of the power grid dispatching automation system is deployed on a specific physical server. Because various applications and services have different demands on resources and unbalanced loads, a lot of resources are wasted. At the same time, the software of the power grid dispatching automation system is tightly coupled with the physical machine, and the flexibility of software deployment and application is poor.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 2, a power grid dispatching automation system based on virtualization technology is provided, the system includes a physical resource layer, a virtualized resource management layer, a system application layer and a user layer; the physical resource layer provides a virtualization resource management layer The physical carrier, the virtualized resource management layer provides resources for the system application layer by virtualizing the resources of the physical resource layer, and the system application layer provides system applications for the user layer to use.

The physical resource layer includes computing resource modules, storage resource modules and network resource modules.

The physical resources include computing resources, storage resources and network resources; the computing resources include servers and PCs, the storage resources include hard disks and disk arrays, and the network resources include switches, routers, and network policy configurations.

The virtualized resource management layer includes a virtualized service layer and a virtualized management layer.

The virtualization service layer virtualizes computing resources, storage resources, and network resources, and provides them to the virtualization management layer in a service-oriented manner. The virtualization management layer manages service-oriented virtual resources, including virtual machines management, elastic resource management, load balancing management and security management.

Virtual machine management includes deploying, starting, shutting down, snapshotting, deleting and migrating virtual machines.

For each application, its operating environment and resource requirements are different. It is necessary to create a type of virtual machine image template for each type of application. When the application is needed, it can be quickly deployed with simple configuration. The lifecycle management of applications is accompanied by the lifecycle management of virtual machines, enabling virtual machines to be started, suspended, shut down, migrated, snapshotted, deleted, etc.

Compared with a single application, elastic resource management mainly realizes the on-demand allocation of resources. For the entire cluster, it needs to realize load balancing on the entire cluster, and dynamically adjust according to the load of the physical servers in the cluster. When the load of a certain physical server is too high, the elastic resource management software will select the virtual machine and the host physical machine to be migrated according to a specific algorithm, and then perform the migration without affecting the operation of the application during the migration process. When the overall load of the physical server is not high, the virtual machine can be migrated to a relatively concentrated physical machine, and then the unused physical server can be temporarily shut down to reduce resource consumption. When the application virtual machine does not work for a period of time, the virtual machine can be shut down.

The system application layer includes dispatch planning application modules, dispatch management application modules, real-time monitoring and early warning application modules, and safety check application modules.

The user layer includes dispatchers and operation and maintenance personnel.

Virtual machine management is the core of the entire system, and it is the basis for realizing elastic resource management. Virtual machine management mainly realizes four functions. One is to realize the life cycle management of virtual machines, including deploying virtual machines, starting virtual machines, shutting down virtual machines, taking snapshots of virtual machines, deleting virtual machines, and migrating virtual machines. Virtual machine image management can provide different virtual machine image templates according to the resource and environment requirements of different types of applications, and realize the rapid deployment of applications, such as monitoring control and data acquisition (supervisory control and data acquisition of power grid dispatching automation system, Scada) system virtual machine mirroring and network analysis virtual machine mirroring; the third is to provide monitoring functions for the entire cluster, including three levels of clusters, physical servers, and virtual machines, mainly cpu and memory load; the fourth is to monitor the deployment on virtual machines business monitoring and management. Taking the deployment of the SCADA virtual machine of the power grid dispatching automation system as an example to illustrate the deployment of the virtual machine and its life cycle process is shown in Figure 3.

When deploying a SCADA virtual machine, you first need to check the virtual machine template library to see if the template and image of the virtual machine exist. If there is no template and image for the virtual machine, you need to create a virtual machine template and image. When making a virtual machine image, you first need to resource the SCADA virtual machine Configure, then install the operating system, and then install the software required by the SCADA system, so that the virtual machine image is completed. If the SCADA image already exists, it can be deployed directly. For the deployed virtual machine, operations and management such as starting, shutting down, migrating, and taking snapshots of the virtual machine can be performed.
