Keeping the path of smart grid moving forward, NR has developed innovative solutions for electric distribution networks based on state-of-the-art software and hardware technologies. PCS-9000 Distribution Management System (DMS) is designed for distribution control centers around the world. PCS-9000 DMS provides integrated functions and advanced applications for the control, management, analysis and optimization of day-to-day operations.
As a complete solutions provider, NR can undertake distribution network automation planning, system design, software/ hardware installation and commissioning, project management, engineering, maintenance and after-sale services. NR provides customized services and professional technical support for global customers.
PCS-9000 DMS is a state-of-the-art distribution management system which fully complies with IEC 61970 and IEC 61968 standards. Furthermore, it provides a unified environment and the required functions to enhance the management efficiency of distribution network.
PCS-9000 DMS achieves a complete integrated solution for automation of dispatching by blending powerful operations and services with a real-time management system. In addition, practical application analysis features facilitate secure, efficient and effective day-to-day operations and enhance flexibility and profitability. PCS-9000 DMS uses SCADA data as the base data and implements Geographic Information System (GIS) as the display platform.
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
NAO 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 following functions are provided:
Network modeling
Network topological analysis
Fault Location, Isolation and System Restoration (FLISR)
State Estimation (SE)
Power flow calculation
Short Circuit Analysis (SCA)
Automatic Volt-VAR Control (AVC)
Optimal feeder reconfiguration
Load Forecasting (LF)
Load management
Dynamic coloring
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
Worksheet customization management
Operation rule customization management
Worksheet authority and operation configuration 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
Trouble call management system is a customer information system designed to process/analyze customer trouble calls. The Customer Service Representative (CSR) can register/process customer trouble calls and retrieve customer information.
The following data can be acquired:
Topology model data for power grid equipment
Real-time SCADA data
Automatic Meter Reading (AMR) system data
History trouble call data
History records for equipment failures
Equipment parameters
Based on all the above data, PCS-9000 trouble call management system can find out outage reasons, optimize trouble call processing, as well as determine outage locations. Therefore, outage duration can be minimized, excellent services can be achieved.
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
Operation analysis and validation
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
FA technology enables fast and versatile real-time topology calculations based on the internal relations between devices.
