Product overview:
The energy management system is designed based on a standardized platform. It has summarized and absorbed the successful development and engineering experience of several mature systems, summarized the current micro grid architecture through the existing micro grid definitions and demonstration projects at home and abroad, and adopted a number of new technologies. It is a set of energy management system for smart grid that is specially developed for the development trend of micro grid application technology. The system is oriented to micro grid monitoring, control, analysis, operation, decision-making and management, follows IEC international standards, is based on Unix/Linux/Windows hybrid platform architecture, integrates dispatching automation, distribution network automation, substation centralized monitoring application and analysis functions, and can provide monitoring and control functions for micro grid systems containing distributed power supplies and energy storage units such as wind power generation and photovoltaic power generation.
This system can greatly reduce the investment in the software and hardware of the microgrid automation system. The database and interface are unified, the system is easy to maintain, expandable, and data sharing is convenient. It really promotes the improvement of the microgrid automation level and ensures the safe, stable, and economic operation of the microgrid.
Performance characteristics: Compared with other domestic systems, the system has the following characteristics:
(1) It follows the IEC 61970 energy management system interface specification, IEC 61968 distribution network management system interface specification, and IEC 61850 substation network communication standard, providing international standardized openness. The energy management system has expanded the Common Information Model (CIM) on the basis of IEC61970, and established a variety of distributed generation models such as photovoltaic, wind power, energy storage, etc. On this basis, a complete micro grid public information model has been established and applied to the design of the energy management system. Achieve the standardization and componentization of the system, make the system more open, realize the plug and play of the third-party application functions or application systems that follow the corresponding standards, provide support for the data and application integration of the power grid dispatching system, and realize the sharing of models, parameters and data.
(2) The integrated energy storage system operation monitoring function The energy management system comprehensively monitors the real-time operation information and alarm information of the energy storage battery, and conducts various statistics and analysis of the energy storage. Through the configurable interface, it can automatically control the energy storage system according to the set curve, and automatically protect the energy storage system according to the configuration parameters, so as to achieve full control of the energy storage.
(3) Realize unattended control and optimal control of micro grid system Through real-time collection and control of distributed power generation, energy storage and load operation data, after setting control parameters, the entire micro grid system can be automatically controlled to achieve human on duty. In addition, the operation efficiency and economic benefits of the microgrid system can be improved by optimizing the control strategy.
(4) LINUX/UNIX based distributed system platform architecture. It realizes cross platform and mixed platform from server to client software and hardware, solves the long-term dependence on a single software and hardware platform, and provides good support for system expansion and hardware upgrade.
(5) Support various mainstream operating system platforms Open and portable system architecture.The system is comprehensively utilized according to the advantages and characteristics of various mainstream operating systems, supports open and portable system architecture, supports SUN, HP, IBM and other mainstream UNIX platforms, and supports the mixed use of UNIX servers and PCs.
(6) The graphic model library integration system based on visualization and full vector The graphic model library integration system based on CIM model is designed according to the principle of power system object oriented, the full vector graphic guidance tool, the integration of graphics and database input, and the corresponding relationship between the equipment on the graphics and the data in the database is established automatically. The graphic model library integration system can automatically establish the network topology system of the entire microgrid according to the connection relationship on the wiring diagram, greatly simplifying the engineering work and maintenance work, and ensuring the correctness of maintenance work, avoiding human errors, ensuring the consistency of graphics, models, and databases, and reducing the time for building and database.
(7) Accident recall and replay model based on panoramic simulation technology This system has the recall capability of all collected data (analog quantity, switching value, etc.), and can completely and accurately record and save the accident state of the power grid. The graphic real scene inversion accident type organically combines the accident record analysis and screen monitoring control, which can truly and completely invert the accident process of the power grid, and the analysis and judgment are more intuitive and clear. The energy management system is mainly used to provide monitoring and control functions for the micro grid system containing distributed power supply and energy storage units such as wind power generation, photovoltaic power generation, micro gas turbine, etc.
