Power dispatching is one of the core businesses of the power industry.
The power dispatch system consists of two parts: dispatch center and dispatch terminal (RTU).
The power dispatch monitoring automation system can collect information on the densely-covered power grid through the distributed remote collection units RTU, which can realize real-time data collection, real-time monitoring and display of power grid operation status, remote control and adjustment, and accident alarm , Limit over/shift alarm, data calculation statistics, work information login, automatic system operation status monitoring, accident recall and other functions.
The power dispatch automation system helps dispatchers to understand and master the power situation in a timely manner, and monitor grid information. Through real-time control of power information, resource allocation can be optimized, and limited power resources can be used and deployed more effectively. The power dispatch automation system is a powerful tool to help the power system operation and dispatch personnel to grasp the operation status of the power grid in time, and to dispatch the system operation in a timely and reasonable manner. It can greatly improve the economic benefits of power grid operation and greatly reduce the operation of dispatchers and substations. The labor intensity of the personnel.
At present, a five-level dispatch management system has been formed across the country. The electric power dispatching data network mainly consists of the national electric power dispatching data primary network, regional secondary network, provincial tertiary network, prefecture-level four-level network and county-level five-level network, covering all levels of dispatching centers and direct-regulated power plants and substations.
At present, the first-level network has basically been completed, the second and third-level network projects are being implemented, and a few provinces and cities have begun to build the fourth-level network. With the completion and gradual maturity of the power dispatch data acquisition system, the transmission and networking of power data has become the focus of the next step.
The use of GPRS wireless data transmission services can effectively use the power dispatch data network to achieve real-time transmission and solve problems that cannot be solved by wired channels. After the power data is transmitted to the control system through the GPRS mobile data network, the corresponding calculation and storage are performed to obtain accurate In quantified real-time, the dispatcher has mastered such information and reacted accordingly. Meet the needs of the development of power dispatch automation.
