PCS-9000 Energy Management System (EMS) is a highly specialized, real-time, computer-based supervisory control system designed to assist electric power system operators in monitoring, controlling, managing and optimizing the power grid reliably and efficiently. With hundreds of licenses deployed in China and all over the world, PCS-9000 EMS is the state-of-the-art solution for optimal grid analysis and operation in regards to security, quality and economy. It adopts an advanced network management, object-oriented database and visualized cross-platform technology. Furthermore, it provides abundant practical applications to manage the expanding energy system and reduce the operation and maintenance costs, while meeting the present and future's ever-changing business requirements.
PCS-9000 EMS is based on the latest IEC61970 standard, providing a unified application platform for large-scale energy management of power utilities. The applications of PCS- 9000 system include SCADA, Automatic Generation Control (AGC), Power Application Software (PAS), Dispatching Training Simulator (DTS), Wide Area Measurement System (WAMS), Operation Management Information System (OMIS) and Web. It can also be easily integrated with other systems which comply with IEC61970 standard. This is in favor of protecting the existing investments and reducing internal information and function redundancy.
Supervisory Control and Data Acquisition (SCADA)
SCADA is a specific application framed on the unified application supporting platform and the most basic application of the EMS system. It is mainly used to implement the high performance acquisition and supervisory control function of real-time data.
The following functions are provided:
Control and Regulation
Sequence of Events (SOE)
Data Calculation and Statistics Assessment
Post Disturbance Review (PDR)
Alarm Event Processing & Recording
Data Blocking and Unblocking
Shift Handover/Takeover Management
Manual Data Enforcement
Area Of Responsibility (AOR)
AGC optimizes and controls the use of generation resources to meet regulatory standard and contractual requirements.
Load Frequency Control (LFC)
LFC Performance Monitor
Unit Test and Sampling
Ultra-Short-term Load Forecast (USLF)
PAS is designed to enhance system safety and economical operation. It analyzes the power system operating status and helps dispatchers to understand operation status of the system.
State Estimation (SE)
Dispatcher Power Flow (DPF)
Short-term Load Forecast (SLF)
Contingency Analysis (CA)
Short Circuit Analysis (SCA)
Optimal Power Flow (OPF)
Automatic Volt/Var Control (AVC)
DTS provides training capability that realistically simulates the power system and interacts with the trainee. DTS can simulate normal/emergency/faulty status and restoration process of the power grid. Therefore, DTS enables trainees to study normal operation, fault treatment and system restoration in a dispatching environment similar to scenarios in actual control center.
Power System Simulation Subsystem
Control Center Simulation Subsystem
By application of WAMS, dynamic behaviors of power grid can be monitored and controlled, considerable economic/ social benefits can be achieved. Moreover, WAMS provides fault disturbance and low frequency oscillation analysis, power grid characteristic analysis, power grid operation status monitoring and accurate dynamic process/behavior recording.
PCS-9000 EMS provides access through standard Web interfaces including HyperText Markup Language (HTML), JAVA Server Pages (JSP) and etc. PCS-9000 Web is maintenance free, and it is capable for remote access via Web Server at office and via internet at home.
OMIS provides integrated and unified operation analysis and management for power grid.
