MIS (Management information System) management information systems, mainly refers to the daily operation of the systems, it enables managers to timely understand the status of the company and all kinds of news, it is the Power enterprise management modernization important symbol.
A typical MIS is a computer network technology, automation software technology, thermal power generation technology and advanced management technology as a whole, to build a multi-level dynamic integrated management system. The system will improve the operation, overhaul and management level of independent power plant, shorten the gap with the international advanced level, and effectively realize the integration of power plant operation and management and control. The subject of MIS is the resource management as the center, taking the cost control as the focus, taking the enterprise increment as the goal.
The main functions of MIS include the following aspects:
1) through the connection with the SIS, the unit DCs and other program control systems, the real-time process data is obtained, so that the upper level leaders understand and master the operation Performance and state of the main auxiliary equipment of the Unit;
2) based on the accumulation of historical data, the model of optimization and fault diagnosis is established, and the operation instruction, tuning and fault diagnosis of the equipment are carried out.
3) The establishment of a unified management platform, integration of the various systems for production management personnel scheduling resources, coordination of plant operations to provide strong support;
4) Provide multidimensional Analysis and query of operation data, realize the decision support to the operation of power plant, and support the connection with the future ERP system, ensure the continuous development of information system;
5) Web-based MIS, which requires a WAN interface to be connected to an external information system.
SIS (Supervisory information System) plant-level monitoring information system, which mainly provides comprehensive optimization services for the real-time production process of power plant. The core of SIS is the real-time database (RTDB), so, as the SIS of the data bridge between the bottom control system and MIS, it can provide multi-level real-time data support for the management. SIS realizes information sharing and real-time information monitoring of whole plant production process.
The main functions of SIS include the following aspects:
1) Real-time data collection and processing in the whole factory;
2) Plant-level production process information monitoring, statistics and analysis;
3) Plant scheduling and unit load optimization allocation;
4) Plant-level and unit-level performance calculation;
5) Equipment Status inspection and maintenance instructions.
In summary, the different points of SIS and MIS are also obvious. First, Sis belongs to the field of real-time production process monitoring, and mis belongs to the category of enterprise management modernization, so their service category is different; second, SIS is very demanding on real-time, and it prefers to get inaccurate data and not accept outdated data, while MIS has no special requirements for real-time.
Finally, the overall system hierarchy of the power plant is shown in 1. It is worth explaining that: MIS and SIS network connection problem. According to the "Power grid and power plant computer monitoring system and dispatching data network security protection Regulations", the security level of the MIS and SIS is different, so, the MIS and SIS should use separate network, in the meantime through their respective data server exchange information.
