摘要
电力系统运行的稳定性和安全性事关重大,三相不平衡是能够影响电力系统安全的重要问题。对称分量法是研究三相不平衡问题的基本方法。本文论述了一种基于FPGA实现对称分量运算的方案,通过分析运算公式引出方案的设计思想,并描述了以浮点复数乘加器为核心的具体实现方法。给出浮点复数乘加器的运行机制后,论述了浮点型乘法器和加法器的结构和执行过程。本方案已通过Altera公司的Cyclone Ⅱ芯片实现。可以快速、精确地实现算法,且实时性强,具有可扩展性。
As the stability and safety of power system operation is very important,three-phase unbalance is an important issue which can impact on the safety of power system.Symmetrical component method is an effective method for analysis of unbalanced three-phase.A scheme about symmetrical components operation was discussed based on FPGA.The design idea is introduced through analyzing operational formula.The implementation method with floating point complex multiply-adder as the core is described.The structure and execution process of floating point multiplier and adder were discussed by analyzing the operation mechanism of multiply-adder.The scheme has been implemented with Cyclone Ⅱ chip EP2 C15 of Altera.It can quickly realize the accurate algorithm,and it has strong real-time performance and extendibility.
