Energy management unit PCS-9000

Overview
PCS-9000 Energy Management System (EMS) is a real-time, computer-based supervisory control system designed to help electric power system operators monitor, control, manage and optimize the power grid. It uses advanced network management, an object-oriented database and visualized cross-platform technology. Deployed under hundreds of licenses in China and internationally, PCS-9000 supports the management of expanding energy infrastructures while helping reduce operation and maintenance costs and meet evolving business requirements.

Standard & Integration
PCS-9000 EMS is based on the IEC 61970 standard and provides a unified application platform for large-scale energy management. It integrates with other IEC 61970-compliant systems to protect existing investments and reduce information and functional redundancy.

Applications

• Supervisory Control and Data Acquisition (SCADA)
• Automatic Generation Control (AGC)
• Power Application Software (PAS)
• Dispatcher Training Simulator (DTS)
• Wide Area Measurement System (WAMS)

• Alarm event processing and recording
• Data blocking and unblocking
• Tagging
• Topological coloring
• Shift handover/takeover management
• Clock synchronization
• Database modeling
• manual data enforcement
• Area of Responsibility (AOR)

Functions - AGC
AGC optimizes and controls generation resource usage to meet regulatory and contractual requirements. Key features include:

• Load Frequency Control (LFC)
• LFC performance monitoring
• Reserve monitoring
• Generation scheduling
• Transaction scheduling
• Unit test and sampling
• Ultra-short-term load forecast (USLF)

Functions - PAS
PAS improves operational safety and economic performance by analyzing system state and assisting dispatchers. Features include:

• Network modeling
• Network topology
• 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)

Functions - DTS (Dispatcher Training Simulator)
DTS provides realistic training simulation of power system and control center operations, covering normal, emergency and fault conditions and restoration processes. Subsystems include:

• Trainer subsystem
• Power system simulation subsystem
• Control center simulation subsystem

Functions - WAMS
WAMS enables monitoring and analysis of dynamic grid behavior, including fault disturbance and low-frequency oscillation analysis, grid characteristic analysis, operation status monitoring and accurate dynamic process recording.

Functions - Web & OMIS
PCS-9000 provides standard web interfaces (including HTML and JSP) enabling maintenance-free remote access via web servers. OMIS delivers integrated operation analysis and unified management for power grids.
