基于任务拆分的继电保护云整定计算方法

大电网继电保护的整定计算涉及大量的故障运算与定值配合计算,当前的整定计算软件计算能力有限,难以满足一体化、智能化整定计算的需求,使用云计算成为新一代整定计算软件的重点研究方向。研究了一种基于计算任务拆分的继电保护云整定计算方法,将大规模整定计算任务拆分至最小颗粒,通过任务代理服务器合理分配计算任务、接收回执,调用云服务器计算池进行故障计算,并在辽宁电网省地一体化整定平台上进行了应用。实践结果表明,该方法不但能够保证整定计算结果的准确,而且可以显著提高整定计算的速度。

Cloud Setting Calculation Scheme of Relay Protection Based on Task Splitting

The large power grid setting calculation of relay protection involves a large number of fault calculations and setting coordination calculations.The current relay protection setting calculation system has restricted computing power,which makes it difficult to meet the needs of integrated and intelligent setting calculation,and to make cloud computing a key research direction for a new generation of setting calculation software.A cloud setting calculation scheme of relay protection based on task splitting is researched in the article.The large-scale setting calculation tasks are split to the smallest particles.The computing tasks are reasonably distributed and the receipts are received through the task proxy server.Fault calculations are carried out by calling the cloud server computing pool.It is applied on the integration setting calculation platform for province and region of Liaoning power grid.Practice results show that this scheme can ensure the accuracy of the setting calculation results,and can significantly increase the speed of the setting calculations.
