WKS-PDMS2000 public power distribution room management system

As a leading supplier of intelligent power distribution products in China, Suzhou Wanlong Electric Group Co., Ltd. provides a professional integrated solution for medium and low voltage intelligent power distribution monitoring and management system for power supply and distribution system-"WKS-PDMS2000 public power distribution room management system". It makes full use of modern electronic technology, computer technology, network technology and field bus control technology, to achieve the power supply and distribution system for centralized monitoring and management and decentralized data acquisition, through telemetry, remote control, remote control, remote control and power quality management, historical data analysis and other advanced functions. The system integrates the functions of protection, control, measurement, fault recording, harmonic analysis, power management, equipment management and network communication. It replaces a large number of discrete secondary devices such as conventional instrument panels, operation control panels and central signal systems. Through the "WKS-PDMS2000 public power distribution room management system" to make the power supply and distribution system equipment running state data, is a set of improve the power system security, reliability and management level of intelligent system.

System Features

1. powerful in addition to the realization of the "four remote" function, strengthen the analysis and management functions.
2. Real-time strong multi-threaded and real-time database technology, with a professional SCADA system kernel.
3. reliability adopts redundant modularization, hierarchical distributed structure and digital communication.
4. security to achieve user management, access rights and time limit control, improve the security and traceability of the system.
5. system is open to support a variety of standard fieldbuses and is compatible with products from most manufacturers at home and abroad (Siemens, Schneider, ABB, GE, etc.). At the same time, the system provides a variety of external data interfaces (OPC Server, Modbus Server, Profibus-DP Slave, etc.) to interconnect with third-party systems.

system composition

According to the principle of distributed control and centralized management, the system is divided into station control layer, front layer and field layer (interval layer). The station control layer and the front layer are communicated by TCP/IP Ethernet, and the front layer and the field layer are connected by fieldbus network. In order to meet the differences in the reliability requirements of different users, the system can adopt a dual-network redundancy structure.

station control layer is located in the monitoring center of the system and is mainly composed of hardware and software. The hardware equipment includes operator station, server, printer, UPS power supply and communication network equipment, etc. The software part includes operating system, database software, power monitoring and management configuration software, etc. The monitoring center carries out centralized monitoring and management of the entire power supply and distribution system (multiple power distribution rooms or box-type substations), and provides standard data interfaces to realize data sharing with other systems (BA, DCS, fire protection systems, etc.).
The front layer equipment is the core component of the system, which is usually distributed in the field distribution room, mainly composed of ST2000 intelligent switch cabinet management unit, network communication equipment, communication network and so on. ST2000 intelligent switch cabinet management unit is responsible for collecting equipment operation parameters and status information, realizing operation management, protocol conversion, data service, and uploading data to the monitoring center and BA system through standard interface.
The field layer mainly includes microcomputer integrated protection device, intelligent circuit breaker, intelligent power measurement and control instrument, watt-hour meter, intelligent I/O equipment, reactive power compensation controller and other intelligent terminal equipment.

System Function

1. system monitoring to achieve "four remote" function (telemetry, remote signaling, remote adjustment, remote control).
2. equipment maintenance and monitoring equipment maintenance parameters, provide early warning of hidden trouble, equipment maintenance and maintenance information records, and provide equipment setting management functions.
3. data management real-time data and historical data dictionary functions to query and print historical data and provide load analysis functions. Provide Excel-based timing and real-time reports (daily reports, monthly reports, annual reports), and can achieve call printing and timing storage, printing.
4. Data Publishing Data Interface, Extended Web Publishing Failure Analysis
5. Network Management (Tagout, Offload, etc.)
6. System Security Management
7. Communication Diagnostics
8. automatic control strategy
