The present invention relates to a system and method for operating an application program for analyzing a power distribution operation system.

The operation of the power system acquires the status information (voltage, current, etc.) of the system through a number of remote power facilities, processes it into information that the operator can intuitively know, and displays it on the screen (HMI).

This allows the operator to monitor the status of the system using the displayed information and to control the status of the emergency at all times.

The analysis application program for the distribution operation system is developed by reflecting the operation strategy and grid cord of the power system operator to solve the problems arising from the function of estimating the state of a simple system. However, specific solutions can be derived, including the operating strategies of different operating entities.

Therefore, it is necessary to provide an operating system environment that can utilize application programs so that application requirements or new applications can be easily applied and are not platform dependent.

Through this, it improves the analysis function of the current distribution management system and has the advantage of using the same existing application programs in the future when introducing new ones, and makes it easier to apply the new application program added.

Therefore, the present invention is to propose a structure and method that can be applied to any operating system by separating the operating environment of the application program not dependent on the operating system.

The problem with the prior art is that the main operation of the distribution system is the state in which the operation of the distribution system has no control or operation according to the status (voltage, current) of the distribution system. There was no requirement for the system status analysis function.

Due to the recent environmental issues, many new and renewable energy sources and new load-type distribution systems are linked, so that stable operation is not possible with only distribution system operation experience. It is emerging as a function of.

However, in order to add such a function, there is a problem in that the current operating system must be completely replaced. In other words, the interpretation function for the processing and transmission of such information is a basic function of the operating system, which involves investment costs, operation maintenance, and stabilization of the system.

The present invention is not dependent on the existing distribution operation system and provides an environment that can provide an analysis function tailored to the current distribution line operating conditions.

In other words, it manages the acquired status information and event (breakdown, etc.) information in a form that can be input by the application program. Provides the ability to manage memory.

Instance Data Manager (21) is composed of application-related tables and property information, etc. that are configured in the DB of the distribution operation system. The Instance Data Manager (21) is obtained from the distribution system and the static DB memory composed of the topology and property setting information of the distribution system. RT Memory to manage the value and App Output Memory to manage the output of the application.

Among the main components, the main memory handler and the massage queue handler are composed of the same module, and the additionally configured memory manager 22 performs the creation, deletion, and management of multiple memory.

This operating system is operated under the condition of distribution system. It is a design considering various situations where distribution system can occur at the same time. In other words, the operation of other healthy lines cannot be abandoned in the event of a failure of any line and the transfer of protective equipment. Therefore, it is designed to create and manage a large number of memories in order to carry out selective application of fault information, deletion of continuous information, continuous measurement of health section, etc., and to multi-run application programs for each operation purpose.

Provides the ability to

Also, if the schedule composed of multiple application programs according to the operation purpose is multiple or single, each control and operation can be performed.

The Application Scheduler 31 performs a function of sequentially driving an application program set in periodic driving. For example, when the operator executes periodic application, the program is executed in order according to the application program set in the database according to the initial or user requirements and continues until the operator's shutdown command is issued.

Task Queue 32 recognizes the event status set in the database except the normal status as a message from the proxy, and sets and executes the application program set for each relevant situation. For example, when receiving a message about a fault, prepare to run an application program related to the fault handling.

The APMan Manager 33 manages the interruption or continuation of the application for sequential or event. For example, upon receiving a failure message from a sequentially running application program, the application program may be interrupted and the failure process may be started.

In addition, it monitors the success or failure of the application program and stops the application in case of continuous failure.

Next, Figure 5 shows a specific structure of the operation manager 40.

The operation manager 40 performs 1) status monitoring and control of each major component, and 2) message communication management of each component.

Each component decides whether to perform its function through communication according to the information received. Therefore, it manages the communication channel between each component and provides the function to monitor the operation status (ex: malfunction, etc.) of the component.

The external communication link 41 communicates with elements added in the application driving environment (e.g., dedicated screen elements related to the output of the application program), and the memory link 42 displays main memory for data displayed or required by these additional elements. Establishes a connection for passing values.

External Manager (43) manages the control or interference of the application in the added component, and ApWatchDog (44) is the connection status of each component (ex: screen, Main Memory Manager, Application Manager, etc.) It provides the function to check and monitor the back.
