Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a parallel computing method for analyzing the safety and stability of a large power grid, including the following steps:

[0028] Step 11. Divide the computing tasks into at least two task sets, and distribute the task sets and the fixed data corresponding to the task sets to each computing node. This process is also called the process of pre-allocation of computing tasks;

[0029] The computing task pre-allocation process consists of three steps:

[0030] (1) Initialize the pre-allocation environment; that is, count the computing environment information of each computing node, including CPU type, number, memory size, etc., and these parameter information will become the basis for pre-allocation reference.

[0031] (2) Pre-allocated computing tasks;

[0032] The pre-allocation of computing tasks refers to planning and allocating computing tasks based on the computing environment information of all computing nodes and...

Embodiment 2

[0053] This embodiment provides a computing platform, including a management node and a computing node; the management node is used to obtain power grid operation data, send the power grid running data to the computing node, and receive the calculation result of the computing node; the computing The node is used to set the task table and the fixed data corresponding to each task in the task table, execute the task according to the grid operation data and fixed data, and transmit the result of the task execution to the management node. For the working principles of the management node and the computing node, refer to the description of Embodiment 1.

[0054] According to the present invention, through data broadcasting, task pre-allocation, timing control and application of large-scale parallel algorithm to calculate the safety and stability analysis of large power grid, the combination of task parallel computing and sub-network parallel computing is adopted to simplify the comp...

Abstract

The embodiment of the invention provides a parallel computing method and a computing platform for security and stability analysis of large power grid, which can solve the problem that the computing and analysis efficiency is lower in the prior art. The parallel computing method comprises the following steps: dividing a computing task into at least two task sets and distributing the task set and fixed data corresponding to the task set to each computing node; sending operation data of a power grid to each computing node; and carrying out parallel commutating through each computing node according to the operation data of the power grid and the fixed data. The computing platform comprises a management node and computing nodes. The invention realizes the analysis on the safety and the stability of a large power grid by applying a large-scale parallel computing method based on data broadcast, task predistribution and time sequence control, adopts a way of combining task parallel computing and subnetwork parallel computing, simplifies the complexity of task schedule, improves the stability of the system and realizes a technical leap from offline computing of a power system to online stable analysis.

Description

technical field [0001] The invention relates to a calculation technology, in particular to a parallel calculation method and a calculation platform for analyzing the safety and stability of a large power grid. Background technique [0002] In the existing power system, in order to realize complementary power supply, various power grids are interconnected across regions to form a large-scale power system covering a wide area. In order to realize the stable operation of the power system, it is necessary for various power grids to work together. However, due to various reasons (such as natural disasters, various emergencies), the operating state of the power grid will still change, which will affect the safe operation of the entire power system. [0003] In order to solve this problem, in the prior art, according to the power operation data and fixed data, two modes of sub-network parallel computing and task parallel computing are used to calculate and analyze the operating st...
