FIG. 1 is a block diagram of a typical power system monitoring and control system. - Referring to
FIG. 1 , a typical power system monitoring andcontrol system 100 includes acalculation handling unit 110, adata storage unit 120, aninput unit 130, adisplay unit 140, and acommunication unit 150. - The
calculation handling unit 110 includes aninformation registration unit 111, a registered-information calling unit 112, acalculation execution unit 113, a calculation result informationstorage handling unit 114, and a calculation result informationdisplay handling unit 115. - The power system monitoring and
control system 100 includes a site acquisition point using RTU and ICCP and a calculation point calculating a new result value through necessary calculation based on an acquisition point. In addition, the acquisition point and the calculation point may be referred to as SCADA points. - Since the calculation point needs repetitive calculation in many cases for its characteristic, it is used according to particular expressions (four fundamental rules of arithmetics, logic, and user definition) regarding repetitive calculation.
- The power system monitoring and
control system 100 defines a calculation expression in each calculation file in order to obtain a calculation point result. The power system monitoring andcontrol system 100 registers the calculation file having a defined calculation expression with thedata storage unit 120 by using theinput unit 130 and theinformation registration unit 111. - In addition, the
system 100 calls information on a calculation file stored in thedata storage unit 120 through the registered-information calling unit 112 and executes calculation according to the calculation expression defined in the calculation file of the called information by thecalculation execution unit 113. In this case, threads are created to correspond to the number of registered calculation files, so many calculation operations are performed together. The threads enables simultaneous calculation by dividing about 25,000 calculation expressions into many calculation files, because it is difficult to define the calculation expressions in a single calculation file. - The
system 100 stores a calculated result in the calculation result informationstorage handling unit 114 and processes data acquired from the site through the calculation result informationdisplay handing unit 115. In addition, thesystem 100 displays processed information on thedisplay unit 140 to enable a user to know it. Thus, it is important to determine whether various calculation operations are correctly performed, but as the number of files defining a calculation expression increases, it is difficult for a user to determine through a method of checking on a console whether a calculation operation is being performed. - It is difficult for the typical power system monitoring and
control system 100 to determine the presence and absence of the error of a calculation expression on a thread created for each calculation file. Since there is little information on registered calculation files and it does not appear on the screen, the user may not determine whether the calculation operation is correct. The user may view only a calculation file name on a console appearing in the calculation execution procedure and a message that the calculation operation is being performed (which is difficult to determine the match of a calculation expression defined in a file). - Also, the calculation expression defines, as a function, mathematical symbols and functions, and expressions used in power engineering. A point uploading data on the site sometimes varies in name or disappears during operation, but the typical power monitoring and
control system 100 does not check regarding the name varying and the point disappearing during operation whether a point defined in calculation script is actually in operation, and does not show related content to the user. - Also, file name and account information are being written into a binary file instead of a database managed by the power system monitoring and
control system 100. Also, information, such as a registration time, a calculation execution time, and number of times calculation is executed is not handled. - Thus, since it is not easy for a user to visually check a thread-dependent calculation execution state in the typical power system monitoring and
control system 100, there is a limitation in that it is difficult to quickly take actions when there is a trouble. - Embodiments provide a power system monitoring and control system having a thread-dependent calculation monitoring function that enables a user to visually check a thread-dependent calculation execution state when calculation for power system monitoring and control is executed in the power system monitoring and control system, and enables an action to be quickly taken when there is a trouble.
- In one embodiment, a power system monitoring and control system having a thread-dependent calculation monitoring function includes: a display unit displaying screen information; a calculation handling unit executing thread-dependent calculation based on a calculation expression defined in a calculation file, and performing calculation handling for generating calculation result information and thread-dependent calculation execution monitoring information to provide generated information as screen information on the display unit; and a data storage unit storing file information for power system monitoring and control, information on the calculation file, the calculation result information, and the thread-dependent calculation execution monitoring information.

- The calculation handling unit may include: an information registration unit registering the information on the calculation file with the data storage unit; a registration information calling unit calling and reading the information on the calculation file registered with the data storage unit; a calculation execution unit performing calculation on a calculation expression defined in the calculation file of called information; a calculation result information storage handing unit enabling a result of calculation performed by the calculation execution unit to be stored in the data storage unit; a calculation result information display handing unit enabling information on the result of calculation performed by the calculation execution unit to be displayed on the display unit; and a calculation execution monitoring information display handling unit generating thread-dependent calculation execution monitoring information for monitoring of calculation execution performed by the calculation execution unit, and enabling generated information to be displayed on the display unit.
- The information registration unit may form a DB in the data storage unit through information registration of the calculation file.
- The information registration unit may have a thread-dependent calculation monitoring function combining an input acquisition point and a calculation point to form a calculation expression to define the calculation expression in each calculation file.
- The calculation execution unit may have a thread-dependent calculation monitoring function generating a thread for each calculation file registered, to simultaneously perform calculation.
- The thread-dependent calculation execution monitoring information may include information on one or more of a calculation status indication, an order of registered calculation expressions, a file name of a file in which a calculation expression being currently performed is defined, a registration account, a registration time, a time when a calculation expression starts, a time when a calculation expression ends, a number of times all calculations are performed, the number of times valid calculation is performed, the number of times erroneous calculation is performed, a notification message for registering a calculation expression, and a calculation start/stop button.
- The information on the calculation status indication may include: a first calculation status indicating that calculation script is a valid operation, a second calculation status indicating a status in which calculation has not been performed because there is an operand different from a DB stored in the data storage unit among calculation expressions in calculation script which is registered with the data storage unit and is being performed; and a third calculation status indicating a status in which a calculation expression temporarily stops by a user request.
- The third calculation status may include a status which is registered with the DB but in which a preliminary work enabling calculation is not ready, or a status in which calculation of calculation script is not performed by a specific condition.
- The specific condition may include an erroneous operation of a thread, or execution disability of calculation script.

FIG. 2 is a block diagram of a power system monitoring and control system having a thread-dependent calculation monitoring function according to an embodiment of the present invention. - Referring to
FIG. 2 , a power system monitoring andcontrol system 200 having a thread-dependent calculation monitoring function according to an embodiment of the present invention includes acalculation handling unit 210, adata storage unit 220, aninput unit 230, adisplay unit 240, and acommunication unit 250. - The
calculation handling unit 210 executes thread-dependent calculation based on a calculation expression in a calculation file, and handles calculation for generating calculation result information and thread-dependent calculation monitoring information to provide generated information as screen information to thedisplay unit 240. - The
data storage unit 220 stores various pieces of file information, calculation file information, calculation result information and thread-dependent calculation execution monitoring information for the operation of the power system monitoring andcontrol system 200. The information is stored in the form of a DB. - A calculation file includes a calculation expression defined by combining an acquisition point received from a user and a calculation point. The calculation expression defines, as a function, mathematical symbols and functions, and expressions used in power engineering.
- The thread-dependent calculation execution monitoring information is information for displaying whether thread-dependent calculation is being validly performed, and may include, e.g., a calculation status indication, the order of registered calculation expressions, the file name of a file in which the calculation expression being currently performed is defined, a registration account, a registration time, a time when a calculation expression is performed (starts/ends), the number of times all calculations are performed, the number of times valid calculation is performed, the number of times erroneous calculation is performed, a notification message for registering a calculation expression, and a calculation start/stop button.
- Thus, even if a point uploading data on the site varies in name or disappears during operation, it is possible to check regarding the name varying and the point disappearing during operation whether a point defined in calculation script is actually in operation. In addition, when there is a request from a user, it is possible to provide requested information to the user.
- Also, since the power system monitoring and
control system 200 stores calculation execution monitoring information as well as various pieces of file information for operation in thedata storage unit 220, it is possible to monitor a thread-dependent calculation execution state in real time or hourly. - For example, it is possible to authenticate an erroneous point by matching a point name defined in calculation script with the name of an actual operation point stored in a database (DB). It is possible to check presence and absence by matching the name of a site operation point defined in the DB with the name of a calculation point defined in calculation script. Also, thread-dependent point validity may be authenticated.
- The
calculation handling unit 210 may include aninformation registration unit 211, a registered-information calling unit 212, acalculation execution unit 213, a calculation result informationstorage handling unit 214, a calculation result informationdisplay handling unit 215, and a calculation execution monitoring informationdisplay handling unit 216. - The
information registration unit 211 registers, with thedata storage unit 220, files in which calculation expressions are defined, and the files stored in thedata storage unit 220 form a DB. - The
information registration unit 211 may combine an acquisition point received from a user through theinput unit 230 and a calculation point to make a calculation expression, and define as each calculation file. Theinformation registration unit 211 may define the file name of a calculation file to register, a registration user, and expression details in binary form, in a calculation file, e.g., “regist.cfg”, when a defined calculation file is registered with thedata storage unit 220. - The registration
information calling unit 212 calls and reads information on the registered calculation file “regist.cfg”. - The
calculation execution unit 213 performs calculation on a calculation file of information called by the registrationinformation calling unit 212 and performs calculation according to a defined calculation expression in this case. The calculation file includes calculation script in which a calculation expression is defined. In this case, thecalculation execution unit 213 may create a thread for each file registered and perform simultaneous calculation. - The
calculation execution unit 213 may read about 25,000 calculation expressions defined in the calculation script to perform calculation. - The calculation result information
storage handling unit 214 stores, in thedata storage unit 220, a result of calculation performed by thecalculation execution unit 213. - The calculation result information
display handling unit 215 displays, on the display unit, the result of calculation performed by thecalculation execution unit 213. - The calculation execution monitoring information
display handling unit 216 may display, on thedisplay unit 240, calculation execution monitoring information that a user may visually check. The calculation execution monitoring information may include a calculation execution monitoring screen that includes various pieces of information for monitoring calculation execution. -
FIG. 3 is a flowchart for explaining how to execute a thread-dependent calculation monitoring function in a power system monitoring and control system having the thread-dependent calculation monitoring function according to an embodiment of the present invention. - Referring to
FIG. 3 , theinformation registration unit 211 registers, with thedata storage unit 220, information on a calculation file that includes a calculation expression defined by combining an acquisition point and a calculation point in step S1. - The registration
information calling unit 212 calls information on a calculation file registered with thedata storage unit 220 in step S2. - The
calculation execution unit 213 executes calculation of a calculation file of information called by the registrationinformation calling unit 212 in step S3. - The calculation execution monitoring information display handling unit 26 displays, on the
display unit 240, calculation execution monitoring information in step S4. - The calculation execution monitoring information
display handling unit 216 may display, regarding calculation files registered with thedata storage unit 220, a registration file name, a registration account, a registration time, a time when calculation is performed, the number of all calculation expressions defined in a file, and the number of calculation expressions having errors while calculation is performed, on thedisplay unit 240 to provide to a user a notification that calculation is being correctly performed. - Thus, a user may check the number of errors displayed on the
display unit 240 when there are expressions having errors while calculation is performed, and thus quickly solve the limitation. - The calculation result information
storage handling unit 214 enables calculation result information to be stored in thestorage unit 220 in step S5. - Then, the calculation result information
display handling unit 215 displays calculation result information on thedisplay unit 240 in step S6. -
FIG. 4 shows an example of a thread-dependent calculation execution monitoring screen provided in a power system monitoring and control system having a thread-dependent calculation monitoring function according to an embodiment of the present invention. - Referring to
FIG. 4 , a calculationexecution monitoring screen 216 a may include acalculation status indication 11, the order of registeredcalculation expressions 12, thefile name 13 of a file in which the calculation expression being currently performed is defined, aregistration account 14, aregistration time 15, atime 16 when a calculation expression starts, atime 17 when a calculation expression ends, the number of times all calculations are performed 18, the number of times valid calculation is performed 19, the number of times erroneous calculation is performed 20, anotification message 21 for registering a calculation expression, and a calculation start/stop button 22. - The
calculation status indication 11 may display a calculation execution status. Information on the calculation status indication may be divided into a plurality of calculation statuses according to the ratio of the number of times all calculations are performed to the number of times erroneous calculation is performed. - For example, it is possible to indicate green 11 a,
orange 11 b and red 11 c according to the ratio of the number of times all calculations are performed to the number of times erroneous calculation is performed. - For example, when the ratio of the number of times all calculations are performed to the number of times erroneous calculation is performed is 10% or higher, it is determined that there is a trouble and thus the color of the
calculation status indication 11 may be changed from green to red. - Also, information on the calculation status indication may be divided into a plurality of calculation statuses according to the presence and absence of a calculation execution operation.
- For example, the green 11 a may indicate that currently registered calculation script is a valid operation. The orange 11 b may indicate a status in which calculation has not been performed because there is an operand different from a DB stored in the
data storage unit 220 among calculation expressions in registered calculation script being performed. The red 11 c may indicate a status in which a calculation expression temporarily stops by a user request. The status indicated by the red 11 c may include, e.g., a status which has been registered with the DB but in which a preliminary work enabling calculation has not been ready. The status indicated by the red 11 c may include, e.g., a status in which the calculation of calculation script has not been performed by a specific condition. In this case, an example of the specific condition may include the erroneous operation of a thread or the execution disability of calculation script. - According to the present invention, it is possible for a user to monitor in real time whether each calculation file registered with a power system monitoring and control system is being correctly performed, and to quickly take actions where there is a trouble.
- Also, even if a point uploading data on the site varies in name or disappears during operation, it is possible to check regarding the name varying and the point disappearing during operation whether a point defined in calculation script is actually in operation.
- Also, when there is a request from a user, it is possible to provide requested information to the user.
- Also, since various pieces of file information for the operation of the power system monitoring and control system and thread-dependent calculation execution monitoring information are stored in the data storage unit in the form of a DB, it is possible to monitor a thread-dependent calculation execution state hourly.
- Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
