3 Terms and definitions
For the purpose of this document, terms and definitions defined in DL/T924-2005 AND the following terms and definitions shall apply.
3.1
Realtime supervision and management information system
Information system that supervises and manages the production process through production process realtime/ historical data platform for power generation enterprises based on multiple power plants (companies).
3.2 Supervisory information system for plant level; SIS
Realtime supervision and management information system that service for realtime production process comprehensive optimization of the whole plant through production process realtime/ historical data platform for thermal power plant.
[Definition 3.1 in DL/T 924-2005]
3.3
Function computer and client computer
Computers or servers with SIS application functions and management functions are called function computers, including database servers, application software function computers or servers, system backup servers, anti-virus servers, maintenance and management computers, etc. Other computer working stations in the system are called client computers. [Definition 3.2 in DL/T 924-2005]
4 General
4.1 The implementation of the system shall be able to be done step-by-step according to the actual requirements and technology development plan-design. The system shall insist on reliable, versatile and scalable principles.
4.2 The metrological unit shall comply with national standards and provisions for common physical and legal metrological units. The data-marker design shall follow the requirements of DL/T 950.
4.3 The data scale of realtime/historical database shall be determined according to requirements of system construction and development. The collection content and collection code of data shall be standardized and unified; the data information processing shall be standardized and unified; the accuracy, comparability and maintainability of data at measuring points shall be ensured; the function of checking the data quality shall be provided to facilitate the check and maintenance of data.
hot plug/unplug redundant power supplies and hot-plug / unplug redundant fans. Non-core switches can use parts according to the specific situation.
5.2.2 Database servers
Use redundant arrays of inexpensive disks shared by database servers; it can use independent storage systems shared by networks. It can use database server systems with redundancy configuration or fault tolerant database server systems. Database server systems with redundancy configuration shall support the automatic failure switch-over through cluster working mode.
5.2.3 Data source interface stations at power generation enterprises
5.2.3.1 Use redundancy mode; the caching of data shall be able to include at least production process information within one week; Support the wake-one-LAN and be able to send the data in buffer memory to the database server automatically when the network communication returns to normal.
5.2.3.2 Remote communication shall be able to do with collection stations at power plants; the unit running information shall be able to obtain from the collection stations at power plants in real time.
5.2.4 Data collection stations at power plants
5.2.4.1 Use redundancy mode; the caching of data shall be able to include at least production process information within one week; Support the wake-one-LAN and be able to send the data to caching them in the database server automatically when the network communication returns to normal.
5.2.4.2 Do not alter and configure the control internet under power plants, Do not control the manufacturing process directly; it shall not affect the control function of the underlying production control internet.
5.2.5 Function computers and client computers
Set different operations and system access limits according to the functions of the function computer and client computer. Client computers shall only be equipped with basic supervision and inquiry functions to production processes without system management function.
