背景技术
本发明中提到的储能系统是指由多个单体超级电容(后文简称超级电容)构成的储能系统。储能系统的可靠性,取决于每一超级电容的可靠性和每个超级电容之间电气连接的可靠性。由于超级电容在出厂时各性能参数存在一定的差异,随着使用时间的增长,及使用的环境温度、充放电倍率和循环使用次数等因素的影响,会使超级电容的性能会出现不同程度的衰减,增大储能系统内单体间性能参数的差异。在具体实施中,单体间性能参数差异越大,则越容易出现单体过电压等问题。基于上述情况,通常需要对储能系统进行维护和检修。
现有技术中,对储能系统进行维护和检修的依据是对超级电容进行在线检测,检测的性能参数主要是超级电容的内阻、容量和漏电压,检测的过程主要是通过设定阈值,当超过阈值时,故障报警,进行维护检修。但是超级电容仅仅是储能系统中的一个单体,其性能参数虽然影响储能系统的健康状态,但是并不能代表整个储能系统的健康状态。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下,所获得的所有其他实施例,都属于本发明保护范围。
本发明的核心是提供一种用于储能系统的健康状态在线分析方法、装置及介质,用于合理、准确地对储能系统的健康状态进行检测从而提高储能系统的可靠性和延长其使用寿命。
为了使本技术领域的人员更好地理解本发明方案,下面结合附图和具体实施方式对本发明作进一步的详细说明。
图1为本发明实施例提供的一种用于储能系统的健康状态在线分析方法的流程图。如图1所示,该方法包括:
S10:获取储能系统中的模块级运行参数、模组级运行参数、电源级运行参数以及超级电容运行参数。
两个超级电容并联构成模块级,多个模块级串联构成模组级,多个模组级串联后最终构成储能系统。基于储能系统的构成方式,超级电容的性能必然影响储能系统的性能,但是如果仅仅是基于超级电容的性能来评价储能系统的性能的话,则容易造成评价结果失真。
本实施例中除了超级电容运行参数外,还将模块级运行参数、模组级运行参数以及电源级运行参数均作为评价储能系统性能的因素,从而能够更加直观和准确地反映储能系统的性能。
需要说明的是,模块级运行参数、模组级运行参数、电源级运行参数以及超级电容运行参数的类型本实施例不作限定。
S11:依据预设的健康状态分析逻辑得到储能系统的健康状态。
由于选取不同的模块级运行参数、模组级运行参数、电源级运行参数以及超级电容运行参数,则对应的健康状态分析逻辑也是不同的,需要说 明的是,健康状态分析逻辑可以根据实际情况确定,只要在该逻辑中能够考虑到模块级运行参数、模组级运行参数、电源级运行参数以及超级电容运行参数即可。
另外,储能系统的健康状态可以分为若干个等级,例如2个等级,优选地本发明选取个等级,具体是健康状态、亚健康状态和非健康状态,其中,亚健康状态是临界与健康状态和非健康状态之间的一种状态,也就是说当前储能系统不是健康状态,只是出现了一些异常的预兆,如果继续使用不维护的话,则可能就演变为非健康状态。可以理解的是,健康状态的划分不影响本技术方案的实施。
本实施例提供的用于储能系统的健康状态在线分析方法,首先是获取储能系统中的模块级运行参数、模组级运行参数、电源级运行参数以及超级电容运行参数,然后依据预设的健康状态分析逻辑得到储能系统的健康状态。由于本方法中除了采用超级电容运行参数外,还采用了模块级运行参数、模组级运行参数、电源级运行参数这三种参数,因此,通过多表征参数的综合判断能够确定电源健康状态的变化的趋势,提前对不健康的超级电容进行维护检修处理,降低故障的概率,从而更加合理和准确评价储能系统的健康状态。并且,上述参数都是通过现有的储能系统就可以得到的,不需要对储能系统做改进,降低了硬件成本。
在上述实施例的基础上,作为优选地实施方式,模块级运行参数中的非异常信息包括模块电压,模块级运行参数中的异常信息包括电压过压预警信号、电压过压报警信号、电压欠压预警信号、电压欠压报警信号、温度预警信号和温度报警信号;
模组级运行参数中的非异常信息包括模组电压、模组温度;
电源级运行参数中的非异常信息包括电源电压、电源温度、电源电流,电源级运行参数中的异常信息包括正极熔断器故障信号、负极熔断器故障信号、24V隔离电源故障信号、浪涌保护器故障信号、风扇故障信号;
超级电容运行参数具体包括超级电容温度变化率和超级电容电压变化率参数。
需要说明的是,上述参数可以通过CMS管理系统获取,其中预警信号和报警信号是不同的,预警信号是通过协议中以预警的方式得到的信号,该方式表明对应的器件处于轻度故障,而报警信号是通过协议中以报警的方式得到的信号,表明对应的器件处于严重故障。本实施例中的模组温度具体是电路板温度和电容温度,可以通过温度传感器获取,请参见现有技术,本实施例不再赘述。
在获取电源温度后,需要先对温度数据进行预处理,然后采用Tukey’s test方法进行异常检测。如果检测结果为异常,则产生一条新的异常信息。如果检测结果为正常,则不产生异常信息,最后通过异常信息确定电源温度的评价结果。
电源温度的预处理过程参考动量梯度下降法的预处理部分,可以将数据进行平滑处理,对历史数据和当前数据进行加权平均以减轻错误数据的影响。具体公式如下所示:
V T=β·V T+(1-β)·T
Figure PCTCN2018121451-appb-000001
其中,V 0=0,T为T时刻的储能电源温度,V T为前T时刻之前的加权平均温度,V T corrected为修正后的前T时刻之前的加权平均温度,t为第t次迭代,β为系数,β∈(0,1),一般取0.9,可视实际情况进行调整。
最后,在本实施例的基础上,在其他实施例中,还可以包括:均压模块故障信号、电压采样错误信号、温度采样错误信号、电压数据异常信号等作为分析储能系统的参数,本实施例不作赘述。
本实施例中选取上述参数作为模块级运行参数、模组级运行参数、电源级运行参数和超级电容运行参数,更具代表性,且这些参数均可通过现有的储能系统获取,无需改动储能系统的硬件结构。
在上述实施例的基础上,作为优选地实施方式,依据预设的健康状态分析逻辑得到储能系统的健康状态具体包括如下几个子步骤。图2为本发 明实施例提供的一种依据预设的健康状态分析逻辑得到储能系统的健康状态的流程图。
步骤一:通过聚类方法对模块级运行参数中的非异常信息、模组级运行参数中的非异常信息以及电源级运行参数中的非异常信息进行聚类分析得到对应的健康等级。聚类分析方法包括很多种,其中K-means法作为快速聚类法(又称动态聚类法)中最常用的一种,由于在计算速度上具有无可比拟的优势,已经被广泛应用。优选地,聚类方法可以选取K-means聚类方法。以下通过K-means聚类进行举例说明。
假设当前数据集为D,(D={模块级,模组级,电源级}),D有对应的非异常信息,具体是模块级运行参数中的非异常信息(模块电压、模块温度)、模组级运行参数中的非异常信息(模组电压、模组温度)、电源级运行参数中的非异常信息(电源电压、电源温度、电源电流),通过K-means聚类方法利用非异常信息进行聚类,对当前D的各个具体对象进行分类得到对应的健康状态。
实际应用中,由于各个超级电容内部参数不完全一致,所以不会出现理想状况下的各超级电容同步老化现象。假设算法初始运行时,超级电容各级初始状态均为健康。
随着时间轴的移动,会出现第一阶段:全部具体对象均处于健康状态,此时K=1;第二阶段:部分具体对象处于健康状态,部分具体对象处于亚健康状态,此时K=2。由先验知识可知,簇内点数多的点处于健康状态,簇内点数少的点处于亚健康状态。
该方法取定K个类别和选取K个初始聚类中心,按最小距离原则将各点分配到K类中的某一类,之后不断地计算类心、调整各点所属的类,最终使各点到其判属类别中心的距离最小。
给定数据集合D={x1,x2,…,xn},下面是K-means算法的聚类过程:
1.设置类数目K的值;
2.初始化类中心Z=(Z1,Z2,…,ZK),循环开始;
3.计算每个点与每个类中心的距离,并把各个点分配到与之最近的类中;
4.根据每个簇中的点重新计算类中心;
5.判断类心是否发生改变或者是否达到最大迭代次数,是则结束循环,否则继续循环,重复3、4步骤。
步骤二:利用预先设定的电压变化率亚健康阈值对超级电容电压变化率参数进行判断得到对应的健康等级。
超级电容的健康状态与超级电容的电压变化率存在着紧密的联系,设定一个电压变化率亚健康阈值,如果超过设定阈值,则判定超级电容处于亚健康状态,否则为健康状态。需要说明的是,本步骤中的电压变化率亚健康阈值可以根据实际情况设定,本实施例不作限定。
步骤三:利用预先设定的温度变化率亚健康阈值对超级电容温度变化率进行判断得到对应的健康等级。
超级电容的内阻及电气连接与模块的温升存在着精密的联系,设定一个温度变化率亚健康阈值,如果超过设定阈值,则判定超级电容处于亚健康状态,否则为健康状态。需要说明的是,本步骤中的温度变化率亚健康阈值可以根据实际情况设定,本实施例不作限定。
步骤四:按照故障的分类方法对模块级运行参数中的异常信息以及电源级运行参数中的异常信息进行判断得到对应的健康等级。
模块级运行参数中的异常信息包括电压过压预警信号、电压过压报警信号、电压欠压预警信号、电压欠压报警信号、温度预警信号和温度报警信号;电源级运行参数中的异常信息包括正极熔断器故障信号、负极熔断器故障信号、24V隔离电源故障信号、浪涌保护器故障信号、风扇故障信号。具体的故障的分类方法为:按故障的严重性和发生故障的数量分类。
按故障的严重性,可分为轻度故障(可为协议中的预警信号)和严重故障(可为协议中的报警信号、故障信号和异常信号)。例如,当前的故障有轻度故障1,轻度故障2,轻度故障3,严重故障1,严重故障2。
则若轻度故障条数累计达到1-2条,则发生轻度故障;
若轻度故障条数累计达到3条,则转为严重故障;
若严重故障条数累计达到1条或者1条以上,则发生严重故障。
需要说明的是,上述对于故障的分类方法仅仅是一种具体实施方式,还可以采用其它的分类方法,本发明不再赘述。
步骤五:按照表1对应的分类方法,对由于异常信息引起的故障等级以及非异常信息对应的健康状态进行综合判断得到相应模块对应的健康等级。
表1状态分析表
Figure PCTCN2018121451-appb-000002
按照表1对应的分类方法,如何得到对应的健康等级,以当前D为模块级进行说明。对于模组级、电源级同理,不再赘述。
假设当前模块级处于健康状态,如果当前模块还产生了1-2条轻度故障信息,则当前模块级转为亚健康状态;
假设当前模块级处于健康状态,产生3条以上轻度故障信息,则当前模块级转为非健康状态;
假设当前模块级处于健康状态,如果当前模块产生了1条以上严重故障信息,则当前模块级转为非健康状态;
假设当前模块级处于亚健康状态,如果当前模块产生了1条轻度故障信息,则当前模块级仍为亚健康状态;
假设当前模块级处于亚健康状态,如果当前模块产生了2条以上轻度故障信息,则当前模块级转为非健康状态;
假设当前模块级处于亚健康状态,如果当前模块产生了1条以上严重故障信息,则当前模块级转为非健康状态。
对于上述提到的步骤,每个步骤都能得到一个对应的健康等级,分别表示不同的参数对应的健康等级,最终的储能系统的健康等级就是通过这些健康等级来确定。具体方法如下:
1)若得到的健康等级中包含有至少一个亚健康状态且不包含有非健康状态,则储能系统的健康状态为亚健康状态;
2)若得到的健康等级中包含有非健康状态,则储能系统的健康状态为非健康状态;
3)若得到的健康等级中均为健康状态,则储能系统的健康状态为健康状态。
参见图2所示,作为优选地实施方式,还包括:
若储能系统的健康状态为健康状态,则控制车辆正常运营;
若储能系统的健康状态为亚健康状态,则控制车辆停止运营,并允许车辆自动运行回库;
若储能系统的健康状态为非健康状态,则控制车辆停止运营,且停止运行,并呼叫救援车辆拖车回库。
需要说明的是,当储能系统的健康状态为亚健康状态时,说明当前储能系统有可能会出现异常,但是当前并未故障,因此,车辆还可以自行回库,不需要救援车辆的帮助,而当能系统的健康状态为非健康状态时,说明当前储能系统已经出现故障,车辆已经无法自行回库,需要有救援车辆的帮助。无论是车辆自行回库还是救援车辆救援回库,都需要对储能系统进行检修以排除故障恢复到健康状态,至于如何检修,请参见现有技术,本实施例不再赘述。
