Assigning data collection and processing tasks to the server, while centralizing the human-machine interface to the client, fully utilizing the advantages of various parts in the network system, achieving high resource sharing, greatly improving the performance of the entire system. In addition, this distributed structure makes the system configuration very flexible, and the expansion and upgrade of the system are also very convenient.

(8) Development System of Web Technology

HKST-SCADA has successfully introduced web technology into power automation systems. Due to the Internet platform based on web technology, the system can break through geographical limitations and truly achieve remote operation.

Main functions

(1) Data collection and processing:

  • Data collection and processing are the foundation of safety monitoring and control in power supply and distribution systems. The monitoring system can collect real-time analog signals of electrical equipment (such as voltage, current, power, electrical degree, frequency, temperature, pressure, etc.) and switching values (opening/closing signals of circuit breakers and isolation switches, equipment operation status, etc.). The monitoring system processes the collected data in real-time, performs rationality verification, upper and lower limit comparison, and various statistical value calculations on the analog quantity, and finally sends it to the real-time database of the system to ensure the real-time and effective changes in the human-machine interface data and historical database data.

(2) Data communication:

  • The system supports communication and networking of over 2000 domestic and foreign brands of intelligent modules/network instruments/protection devices/PLCs/PTUs and other equipment.
  • The system supports OPC devices and can easily communicate and exchange data with other systems (such as higher-level scheduling systems, medium and high voltage systems, etc.).

(3) Operational control

  • The monitoring system divides operational control into three layers: the first layer is a remote centralized control method, located in the main control room,

 

  • Operators can control controlled objects through monitoring the host, and this control method can be set with anti misoperation functions in the software. The second layer is the centralized control method for monitoring sub stations, where operators can control and operate controlled objects through the sub station host, and the control operation can also be set with anti misoperation functions in the software. The third layer is a local control method, which means that the operator can manually operate the switch cabinet directly. For controlled objects, only one of the three control methods is effective at the same time.

(4) Event and alarm handling

  • The content of the alarm includes analog quantity limit exceeding alarm and switch quantity status change alarm. Switch displacement alarm: automatically displayed on the alarm page and distinguished by color. Analog quantity exceeding limit alarm: It can also automatically scroll through the alarm page and list the release information automatically when the alarm is automatically released.
  • Historical event query includes remote control operation events and communication events (communication failures). Historical event query can be classified and queried by date, time, and category.
  • When an alarm occurs, the system can notify the operating user through voice alarm, flashing ******, and automatic pop-up alarm interface.

(5) Historical database:

  • The system adopts an excellent real-time database system, which can choose data storage intervals or save data according to data change rate (when the amplitude of data change reaches the set value).
  • The database adopts efficient compression algorithms to ensure the preservation of large amounts of data.

(6) System security:

  • Dual redundant waste heat backup configuration, with dual machines synchronously saving on-site data. Effectively prevent data loss caused by computer failures.
  • Set multiple user levels and corresponding operation permissions. The control operation has strict password protection, with permission restrictions for different operators. During remote control operation, the system automatically verifies the operator's permissions and password. Only when operators with operating permissions enter the correct password, can they have the right to perform control operations.
  • Anti misoperation function. All remote control operations performed by the operator will pop up a prompt box for operation prompts. The previous remote control operation will only be effective after the user confirms it. And the system automatically records the operation process of all personnel, which can be printed out at any time.
  • The system has good self-diagnosis and self-healing functions, which can diagnose hardware communication faults online. When a fault occurs, it can automatically display the faulty unit on the page. The system continuously attempts to recover at the time set by the user, and during this period, it will not affect the operation of the entire system.

(7) Network structure:

  • The system supports a local area network topology that runs TCP/IP network protocols, which can divide the site into multiple sites. Each site is equipped with corresponding collection servers, and the main station is equipped with historical database servers, alarm servers, etc., forming a truly distributed system. This not only increases the capacity of the entire system but also enhances the efficiency of system data collection.

(8) Page operation:

  • Button based interface operation, supporting page links, jumps, large screens, and navigation maps.
  • Rich graphic library: power grid structure, bar diagrams, etc.

(9) Curve page:

  • Query, display, and printing of daily load curve and historical load curve (selectable time period)
  • The same curve page can display up to 8 curves at once (corresponding to 8 different analog values in the system).

(10) Report page:

  • Historical reports: daily reports, monthly reports, annual reports, and statistical values within the reports (specific styles can be customized according to requirements)
  • Real time report: Real time dynamic display of on-site electricity parameters.
  • The HKST2006 system comes with an Excel like report system, which can generate report types that meet various user needs. The built-in report script language can perform calculate the sum, average, minimum, maximum, and other numerical values related to the report content of rows and columns.
