Problems solved by technology

[0003] In the past, the online and offline evaluation systems were independent in terms of hardware and software, which was beneficial to ensure that the operation of the system would not interfere with each other, but the utilization rate of resources was low, especially the offline evaluation system, which required power system analysts to submit Tasks just start working, so are often idle
On the other hand, the periodic working hours and tasks of the online evaluation system are fixed, and with the cooperation of software and hardware, there is often idle time
At present, there is no related technology to decompose tasks and perform task sequencing according to the computing resources of the online evaluation system of the power system operating status

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The task sorting system for hybrid dispatching of power system running status and offline evaluation in the present invention, such as figure 1 shown, including:

[0018] (1) Calculation period monitoring module: The calculation period monitoring module is used to monitor the calculation period of the power system operation state online evaluation system, update it in time when it changes, and transmit the updated calculation period to the idle time statistics module. This is the basis of the entire system and prepares for task decomposition.

[0019] (2) Online function completion time statistics module: The online function completion time statistics module is used to make statistics on the total time required for the power system operation state online evaluation system to complete all functional tasks in a cycle, and transm...

Abstract

The invention relates to a task sorting system for a hybrid scheduling system for online and offline evaluation of power system operation status, including: a calculation cycle monitoring module, used to monitor the calculation cycle of the power system operation status online evaluation system, and update it in time when it changes; The online function completion time statistics module is used to make statistics on the total time required for the power system operation state online evaluation system to complete all functional tasks in a cycle; the idle time statistics module is used to calculate the idle time of the function modules in the latest period; The task decomposition module is used to decompose the decomposable functional tasks, generate subtasks and transmit them to the task sorting module; Different combinations of tasks start related process execution task combinations. The system is conducive to making full use of the idle resources of the system, and the task sequence is reasonable and efficient.

Description

technical field [0001] The invention relates to the technical field of power system operation state evaluation, in particular to a task sorting system for a hybrid scheduling system for online and offline evaluation of power system operation state. Background technique [0002] The objects of power system operation state evaluation are divided into two types: one is the real-time operation state, and the other is the offline operation state. The real-time operation status evaluation is to conduct status evaluation on the real-time operation data of the power grid, and analyze the current safe and stable operation level of the power grid. Offline operation status assessment is based on offline data provided by power system analysts (such as historical operation data or planned grid data) to conduct status assessment and analyze its safety and stability level. [0003] In the past, the online and offline evaluation systems were independent in terms of hardware and software, w...
