摘要
传统船舶发电状态监测系统,在并网发电状态监测场景下,存在并网发电容量状态判定误差较大,导致实际输出电量与储存电量之间比例异常,扰乱正常并网发电特征逻辑。通过分析并网数据发现,关键在于监测系统对于并网发电系数的判定逻辑阈值,而阈值影响因素由监测硬件与软件算法两部分决定。因此,为了解决上述问题,提出船舶并网发电状态监测系统设计。首先,硬件功能结构进行设计;其次基于硬件获得数据,对并网发电判定阈值进行优化。最后,对输出监测量进行状态系数评估计算,保证输出监测系数的准确性。通过与传统监测系统10组数据的对比表明,提出设计的监测系统,具有数据监测误差小、连续监测稳定性好的特点,更适合船舶并网发电场景的应用。
In the traditional ship power generation state monitoring system,under the grid-connected power generation state monitoring scene,there is a large error in determining the grid-connected power generation capacity status,resulting in the abnormal proportion between the actual output power and the storage power,and disturbing the characteristic logic of the normal grid-connected power generation.Through the grid-connected data,the logic threshold of the grid-connected power generation coefficient is determined by the monitoring hardware and software algorithm.Therefore,in order to solve the above problems,the grid grid monitoring system is proposed.Firstly,the hardware function structure is designed;secondly,optimize the determination threshold of grid-connected power generation based on the hardware acquisition data;and finally,evaluate the output monitoring coefficient to ensure the accuracy of the output monitoring coefficient.The comparison with ten data of traditional monitoring system shows that the designed monitoring system has the characteristics of small data monitoring error and good continuous monitoring stability,which is more suitable for the application of ship grid-connected power generation scenarios.
