针对 SVC（Static Var Compensation，简称 SVC）控制系统的同步问题，通过充分利用控制装置硬件资源，设计了一种新型软件锁相环，在 DSP（Digital Signal Processing，简称 DSP）单元编码实现软件锁相模块，以现场 FPGA（Field Programmable Gate Array，简称 FPGA），锁相计数器替代复杂的积分环节，产生锁相角θ，配合实现锁相。通过仿真和试验验证，软件锁相环在电压不平衡、电压跌落、频率突变等条件下，仍可快速、可靠的实现锁相，减小触发误差，具有良好的应用效果。

With respect to synchronization of SVC (Static Var Compensation)control system,this paper designs a novel software phase-locked loop by making full use of the hardware resource of the control device.Software phase-lock module is realized through coding in the digital signal processing unit (DSP),and the field programmable gate array (FPGA)and the phase-lock counter are used in place of complicated integration element to generate phase-locking angle θto help realize phase locking.Simulation and tests verify that the presented software phase-lock loop still can perform its function quickly and reliably even in case of voltage imbalance,voltage drop or frequency discontinuity,thus reducing triggering error.It produces a good application effect.
