Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] The load analysis and dispatching system of the offshore smart grid of the present invention includes a system configuration unit 1 , a load analysis unit 2 , an event alarm unit 3 , a data acquisition control unit 4 , a monitoring screen unit 5 and a load dispatching unit 6 . Through the system configuration unit 1, enter the basic information of the generator and load equipment in the offshore smart grid, configure the start-stop priority relationship of the generator and load equipment, define events and alarms, and the system configuration unit 1 will transfer the basic information of the generator and load equipment . The start-stop priority relationship is transmitted to the load analysis unit 2, and the event and alarm definition information is transmitted to the event alarm unit 3. The data collection control unit 4 collects the load da...

The invention relates to a maritime smart power grid load analyzing and dispatching system. The maritime smart power grid load analyzing and dispatching system is characterized in that a system configuration unit is used for transmitting basic information and a start-stop priority relation of an electric generator and load equipment to a load analyzing unit and transmitting alarm and event definition information to an event alarm unit; a data acquisition control unit is used for transmitting load data and start-stop status identification, acquired in real time, of the electric generator and the load equipment to the load analyzing unit, the event alarm unit and a picture monitoring unit; the load analyzing unit is used for generating a load dispatching scheme and transmitting the load dispatching scheme to a load dispatching unit which generates a first dispatching signal; the event alarm unit is used for generating an alarm signal and transmitting the alarm signal to the picture monitoring unit; the picture monitoring unit is used for displaying received information in real time and sending a manual control signal to the load dispatching unit which generates a second dispatching signal; the dispatching signals are sent to the data acquisition control unit which is used for controlling the electric generator and the load equipment.
Description
technical field [0001] The invention relates to the field of smart grids, in particular to a load analysis and scheduling system for offshore smart grids. Background technique [0002] The offshore power grid is mainly used to ensure the normal operation of offshore power equipment. Due to its complex power system structure and strong environmental interference, the offshore power system has low stability and difficult maintenance. Keeping the power system running reliably can not only improve mining efficiency, but also greatly reduce maintenance costs. Offshore power grids generally have multiple generator sets running at the same time, and it is necessary to coordinate according to the working mode of each generator set to distribute the load reasonably. Due to the uncertainty of the load required by the power facilities and the limitation of the generator capacity, it is easy for the load provided by the generator to be oversupplied or in short supply, which will lead t...
