摘　　要：提出了一种基于MCU+DSP结构的频率电压紧急控制装置设计方案,通过测量系统频率和电压自动分级投切负荷或解列机组以保证电力系统的功率缺额在最小程度。利用双电压回路进行电压测量,提高可靠性,采用硬件测频,同时为了保证测量的精度和实时性,采用一种新型的频率测量算法实现软件频率测量,算法简单,所需数据窗少。对故障的判断和决策采用多条件、多重闭锁机制,有效防止误动和拒动。A new design scheme of digital frequency-voltage emergency control equipment based on MCU＋DSP structure is Proposed in this paper.It can minimize the system power loss by measuring the system frequency and voltage automatic grading switching load or splitting generating unit.Dual-voltage circuit are designed for voltage measurement,hardware frequency measuring circuit are combining with software frequency measurements which use a simple algorithm required few data windows to ensure the accuracy and real time of measurement.A number of conditions are setting for any failure judgment and decision-making,multi-locking mechanisms are used to prevent malfunction and refused to move effectively.
