SCADA

SCADA subsystem is the foundation of the DMS. Its main objective is monitoring real-time data and controlling distribution equipment such as: feeders, circuit breakers, ring main units, switching stations and distribution transformers. It accomplishes these tasks by analyzing basic real-time data and static data for the entire distribution system. The following functions are provided:

  • Data acquisition
  • Data processing
  • Control and regulation
  • Sequence of Events (SOE)
  • Real-time data calculation and statistics assessment
  • Network topology
  • Historical data
  • Device management
  • Shift takeover management
  • Clock synchronization
  • Authority management
  • System monitoring management

 

Network Analysis and Optimization(NAO)

Network Analysis and Optimization provides distribution power application software, which is based on distribution network topology. Complex software analysis and optimization functions designed for distribution networks provide unified grid modeling of the distribution network complying with IEC61970 CIM model and IEC61968 standard. The NAO consists of the following functions:

  • Network modeling
  • Network topological analysis
  • Fault Location, Isolation and System Restoration (FLISR)
  • State Estimation
  • Power Flow Calculation
  • Short Circuit Calculation
  • Automatic Volt-VAR Control (AVC)
  • Optimal Feeder Reconfiguration
  • Load Forecasting (LF)
  • Load Management
  • Dynamic coloring

Feeder Automation (FA)
  • FA technology enables fast and versatile real-time topology calculations based on the internal relations between devices.
Outage Management System (OMS)

OMS is designed to be computerized and achieve paperless operational management. OMS is based on worksheets and is driven by the workflow engine. It is in favor of reducing the work intensity, improving the work efficiency and quality. OMS is used for day-to-day work tasks, e.g.: outage maintenance, dispatch plan, log management and etc. The following functions are provided:

  • Workflow management
  • Worksheets customization management
  • Operation rule customization management
  • Worksheets authority and operation configuration management
  • Trouble call interaction and management
  • Outage maintenance request management
  • Outage plan management
  • Outage analysis and indices
  • Power supply assurance request management
  • Emergency management
  • Crew and resource management
  • Interactive services between OMS and SCADA
  • Shift management
  • Dispatch log management

Dispatcher Training Simulator (DTS)

DTS is used for dispatcher training examinations, anti-fault exercises and operational analysis. It can simulate diverse power system hypothetical situations such as normal status, fault status, fault identification and restoration processes. DTS enables trainees to study and handle normal operation functions, fault handling and system restoration in an identical dispatching environment to the actual control center. The training simulator operation does not interfere real-time SCADA operations. The following functions are provided:

  • Simulated distribution power system
  • Distribution operator training
  • Anti-fault exercises
  • Outage and restoration training
  • Operations analysis and validation

Enterprise Service Bus (ESB)

ESB is developed to integrate different systems together. PCS- 9000 ESB is event-driven and is supported by XML (eXtensive Makeup Language) message engine. It provides flex software architecture and provides unified coding for the enterprise message system. It supports information exchange and service sharing among PCS-9000 DMS and other systems. The following services are provided:

  • Synchronous messaging service
  • Asynchronous messaging service
  • Point-to-point messaging service
  • Publisher/subscriber messaging service;
  • Complies with IEC 61970 and IEC 61968 standards
    It adopts open architecture and an integrated application platform to meet the expandable requirements of distribution functions.
  • Hardware independent
    The application of hardware independent technology and middleware technology provides a convenient combination of different computer platforms on which to build a distribution management system.
  • Enterprise Service Bus (ESB)
    The PCS-9000 DMS adopts standard Enterprise Service Bus(ESB) to integrate DMS, CIS, GIS, AMR, etc.
  • Graph-Model-Database Integration modeling
    Technology Graph-Model-Database Integration modeling Technology and the unified management system can quickly generate an array of graphs for the power grid, equipment properties and network topology models for SCADA, NAO and DTS applications.
  • Seamless integration design with the GIS display platform
    The GIS display platform is combined with the online real- time system data. Based on the unified data and graphic platform, the GIS and the SCADA graphic systems are integrated in order to provide a real-time display mode identical to the operation mode. All operations and job management can be executed with the assistance of GIS mapping.
