Embodiment Construction

[0022] A method for developing a distributed parallel power flow calculation system based on the PQ method,

[0023] In terms of system design:

[0024] Distributed power flow calculation mainly studies how to distribute and run huge computing tasks on a platform established by multiple computers interconnected through the network.

[0025] Combining the existing StoC network communication method and the communication scheme in ZIGBEE technology, the structural objects of the system and the way of building the grid are conceived so that the system structure design can meet several requirements of cloud computing underlying services such as strong scalability:

[0026] (1): The system organizes computing by establishing a grid. The grid consists of two types of objects: service units and computing nodes. The service unit is the core of the grid, and it is mainly responsible for managing computing nodes, assigning computing tasks, coordinating the computing process of each node...

Abstract

The invention relates to a distributed parallel load flow calculation system development method based on a PQ method. By using distributed parallel calculation as a guiding thought, load flow calculation of a PQ decomposition method is analyzed so as to design and develop a structural system of a distributed parallel load flow calculation system. According to the method, by decomposing a load flow calculation mathematical model and using multiple computers for carrying out parallel calculation, a single-computer calculated quantity is reduced, so that calculation time and a memory occupation quantity are saved. In a calculation process of the method, a conventional PQ decomposition method calculation process is subjected to parallelization, and an integral iterative process cannot be changed. Therefore, compared with an existing method for carrying out distributed load flow calculation in an asynchronous iterative mode, the method disclosed by the invention has the advantages of simplicity and convenience for establishing the mathematical model and small number of iterations, and can greatly save calculation time and improve calculation efficiency.

Description

technical field [0001] The invention relates to a method for designing and developing a power flow calculation system, in particular to a method for developing a distributed parallel power flow calculation system based on the PQ method. Background technique [0002] With the expansion of power grid power flow calculation scale, the requirements of power flow calculation system for computer hardware continue to increase. At present, computer power flow calculation is mainly limited by the processing speed and storage capacity of a single computer. Therefore, how to solve these problems has become a key issue in computer power flow calculation technology. Distributed parallel power flow calculation is one of the methods to solve this problem. With the help of a high-speed communication network, multiple computers are connected, and the computing tasks are allocated to each computer for parallel computing, so as to achieve the purpose of integrating computing resources and im...
