System overview
The software of master station system of dispatching automation system HYRT-2000 power system, it is the power grid dispatching automation software WINDOWS NT/2000/XP operating system and Microsoft SQL Server 6.5/7.0/2000 large distributed relational database management system based on the use of Microsoft Visual C++ 6 development. In addition, the system also uses Client/Server three layer model and Browser/Server computer and network technology, greatly enhanced the system security, robustness and scalability. Plant configuration can facilitate the expansion, data types besides state, usually analog, power statistics and the three belt scale, quantity, amount control regulation, the default type, can also according to the actual needs of users to arbitrarily defined (such as date statistics, monthly statistics of each); types of data volume can be adjusted, no limit; the system has good scalability and openness. Preemptive multi task mechanism, WINDOWS 2000 operating system for multi process and multi thread mechanism, robustness and micro kernel technology and object oriented programming method for SCADA system stability, reliability and real time to provide a favorable environment protection; Microsoft SQL Server large distributed relational database management system to enhance the historical data management, easy to use and practical, and the reliability and consistency of data provides a strong technical assurance.
This system mainly realizes the data acquisition and communication equipment and terminal (such as: Telecontrol equipment RTU, integrated automation communication machine) data acquisition, monitoring and real-time data, processing of historical data, with four remote, SOE, PDR, WEB service, load forecast function. Master station system software is divided into two parts front and back machine, the machine is divided into server and workstation, the machine is connected by 10/100/1000Mbps Ethernet (single network, network can be), system structure is shown in Figure 1 (this system adopts the structure, double double with some work station according to the following structure Description):
According to the different system functions can be divided into: communication device, front-end, and several background machine workstation.
