Power plant automation monitoring system PSA

The PSA power station automation monitoring system is a system software based on the WINDOWS platform developed by Wuxi Schindler for professional monitoring of substation automation at all levels. PSA not only has the data acquisition and monitoring functions of the conventional monitoring system, but also includes the management functions of monitoring, information collection and analysis, video monitoring and fault waveform analysis of the microcomputer protection equipment, and can provide standard data interfaces and management information system interconnection. Open and shared data.

Product Details

System Features

Compared with traditional configuration software, PSA has the following advantages:

— Stability: The system can monitor, operate and handle sudden faults for a long time;

— Real-time: meet the requirements for real-time accidents and events in the station;

— Professionalism: Designed for the requirements and habits of domestic power systems and variable power stations;

— Openness: The system is easy to expand, upgrade and maintain, and it is convenient for users to develop the system twice;

— Convenience: The system has comprehensive functions, standardized user interface, beautiful and practical, easy to learn, easy to use and easy to maintain;

Typical structure of the system

The single-machine system is mainly suitable for the requirements of the system in the station is relatively simple, the system stability and reliability are not high, the system scale is small, and the user's investment in the monitoring system is not large. The entire system is divided into three layers:

1)Spacer layer: The main equipment is a protective relay. It independently completes the protection, measurement, control and communication functions of the protected equipment. In the case of network failure or paralysis in the station, each protection device can still guarantee the uninterrupted execution of the protection function.

2)Communication layer: mainly for communication manager and communication medium. The system is connected to the communication manager via the on-site industrial bus. The communication manager centralizes the communication channels of the secondary devices in all stations and centralizes the data to the host monitoring system through the network. The communication manager can also be replaced by a plug-in card to integrate secondary devices in the station through dedicated communication cards (such as RS422/485, LONWORK, CAN, Industrial Ethernet, etc.).

3)Substation level: The main equipment is the background monitoring host. The background monitoring system is controlled by a computer using a dedicated PSA system software built on the WONDOWS platform. Through the system configuration, the remote control, remote signaling and telemetry of the entire high-voltage power distribution system are completed, and the whole process operation monitoring of the high-voltage power distribution system is realized. The host simultaneously completes the forwarding of real-time data to the dispatching or centralized control center. The remote moving channel can also be provided through the communication manager, and then transmitted to the dispatching system and the centralized control master station system through the MODEM or the network.
