The Npower3000 distribution automation system
System overview
The Npower3000 distribution automation system, is the use of modern computer and communication technology, the real time operation of distribution network, power grid structure, equipment, users and geographical graph information such as integration, constitutes a complete automation system, realize the automation, information distribution network operation monitoring and management. Suitable for 10KV distribution line ring network and the radiant power supply system. Can fully support the distribution network automation and feeder automation system. Including the 10KV substation outlet switch, column coincidence / segment / boundary switch, ring net cabinet, power distribution transformers, power distribution station, open and close, area distribution, compensation capacitors in distribution network equipment running real-time monitoring.
The structure of the system
The Npower3000 distribution automation system consists of main station system, measuring and controlling terminal, communication is composed of three parts.
1, the main station system consists of SCADA subsystem, subsystem of distribution feeder automation subsystem, WEB release
2, control terminal refers to NKR-02 type distribution monitoring terminal
3, communication refers to the communication line control terminal and the main station system and device
The main function of
The main function of a distribution network, the SCADA subsystem:
1, data acquisition
2, data processing
3, control
4, the sequence of events recording (SOE)
5, alarm processing
6, the system clock synchronization and clock
7, channel monitoring and statistics
8, real time database
9, the man-machine contact
10, remote maintenance support
The two main functions of feeder automation subsystem:
1, the normal state functions: data acquisition, operation monitoring, energy forecasting, load transfer, distribution decision for senior should provide real time and historical data of detailed use function.
2, fault condition function: fault location, fault isolation, master station software according to the load and the load capacity of each generation, the formulation of network reconfiguration and restoration of power supply scheme. In the event of failure, fault location and isolation and provides fast recovery strategy, network reconfiguration.
The main function of WEB release subsystem:
3, users can browse function: through the browser for understanding and analysis of the distribution network operation situation, the leadership also can realize remote office automation;
4, based on the WEB remote automation management: can realize remote monitoring through the pages, with workstation application software use function.
Three, NKR-02 type distribution monitoring terminal mainly function:
1, the analog acquisition: can measure three-phase voltage, three-phase current, three-phase power, frequency and temperature simulation quantity.
2, the switch signal acquisition: acquisition of various position signal.
3, remote control output: multi control switch action jump.
4, the protection function: over-current, over-voltage, three-phase multiple coincidence protection function.
5, the function of communication: integrated GPRS communication module hardware support for remote communication, the standard 232, 468 communication ports to support local communication.
Product features
1, the wireless communication: distribution master station and distribution control terminal innovation adoption of wireless wide area network communication the most advanced technology, the use of GSM/GPRS communication based on the network or 3G network, high speed data channel can be quickly and easily build master terminal and the control terminal. To lead the world trend of distribution automation wireless applications.
2, the implementation of fast: Measurement and control technology of power system the company has many years of accumulation, through the effective integration of wireless communication technology, so that a new generation of Npower3000 distribution automation system structure is simplified, the installation is very convenient debugging. The implementation cycle of the whole system of distribution network automation system than other similar type of at least 50% shorter.
3, complete and strong: Npower3000 distribution automation system combined with the company's production of high-voltage switchgear and ring equipment can realize the one or two equipment forming a perfect combination of.
4, the performance to price ratio is high due to the adoption of wireless wide area network technology public solves large range of distribution network covering the data communication problem, and the distribution of the terminal miniaturization, design a variety of functional integration, which makes the whole Npower3000 distribution automation system in the function is stronger than the traditional power distribution automation system, while the system purchase, the implementation and operation and maintenance of comprehensive cost than similar other distribution automation system is also slightly lower about 10%.
The scope of application
First, the user of electric power system Npower3000 system is mainly used in power system 10KV power distribution line ring and radiant power supply system.
The distribution monitoring and management of part function two, large corporate users of the Npower3000 system also applies to the metallurgical, petrochemical, iron and steel, cement, machinery, electric railway, subway, highways, mines, ports and other industry fields.
