目前行业中的电源设备(例如，高压直流电源柜)只配有异常状况发生后的告警系统，并没有提前预警的功能，运维人员很难提前预知故障发生的时间和位置，并且机壳的存在导致设备内部的故障很难被发现，只有在故障恶劣到出现破坏性现象后才能被发现，往往这个时候损失已经无法避免，所以很多严重事故无法及时阻止。
市面上现有的高压直流厂家一直无法解决的问题就是如何避免恶性故障发生，例如电源柜内部故障恶化到一定程度导致着火烧毁设备、机房，对生命和财产造成不可估量的损失。结合高压直流的特点以及行业中的故障发生案例，电源设备的故障都是从搭接点处开始暴露。

图2是根据本公开实施例的一种电源设备的工作状态的调整的流程图，如图2所示，该 流程包括如下步骤：
步骤S202，获取电源设备的第一搭接点的参数信息，其中，所述参数信息包括：电参数、第一温度；
电参数包括但不限于：电流、电压、负载率。
步骤S204，根据所述参数信息确定所述第一搭接点的故障预测信息；
可选地，根据所述参数信息确定所述第一搭接点的故障预测信息，包括：确定所述电源设备的智能保护单元的预测功能是否开启，在所述电源设备的智能保护单元的预测功能开启的情况下，根据所述参数信息确定所述第一搭接点的故障预测信息。
步骤S206，在所述故障预测信息指示所述第一搭接点存在故障的情况下，根据所述故障预测信息调整所述电源设备的工作状态。
上述故障包括：一级故障、二级故障和三级故障，其中，所述一级故障的风险等级小于所述二级故障的风险等级，所述二级故障的风险等级小于所述三级故障的风险等级，或者，所述一级故障的风险等级大于所述二级故障的风险等级，所述二级故障的风险等级大于所述三级故障的风险等级。
在所述一级故障的风险等级小于所述二级故障的风险等级，所述二级故障的风险等级小于所述三级故障的风险等级的情况下，可以理解为，一级故障为轻度故障；二级故障为中度故障，三级故障为重度故障；在所述一级故障的风险等级大于所述二级故障的风险等级，所述二级故障的风险等级大于所述三级故障的风险等级的情况下，可以理解为，一级故障为重度故障；二级故障为中度故障，三级故障为轻度故障。
其中，轻度故障造成恶性事件的概率小于或者等于第一预设概率；中度故障造成恶性事件的概率大于第一预设概率，小于或者等于第二预设概率，电源设备可以通过减少搭接点对应的负载，以降低恶性事件发生概率；重度故障造成恶性事件的概率大于第二预设概率，电源设备可以通过断开搭接点的所有负载，以降低恶性事件发生概率。
通过上述步骤，由于获取电源设备的第一搭接点的参数信息，其中，所述参数信息包括：电参数、第一温度；根据所述参数信息确定所述第一搭接点的故障预测信息；在所述故障预测信息指示所述第一搭接点存在故障的情况下，根据所述故障预测信息调整所述电源设备的工作状态。解决了相关技术中电源设备只配有异常状况发生后的告警系统，只有在故障恶劣到出现破坏性现象后才能被发现，无法避免恶性事件发生的问题，进而达到了提升电源设备的安全性的技术效果。
可选地，上述步骤S204可以通过多种方式实现，本公开实施例中给出了两种实现方式，包括：
1)确定每一电参数对应的第二温度，并确定所述第一温度与每一第二温度的温度差值；根据所述第一温度与每一第二温度的温度差值确定所述第一搭接点的故障预测信息。
可选地，在所述一级故障的风险等级小于所述二级故障的风险等级，所述二级故障的风险等级小于所述三级故障的风险等级的情况下，根据以下方式确定第一搭接点的故障预测信息：在所述第一温度与任一第二温度的温度差值大于第一预设阈值，且小于第二预设阈值的情况下，确定所述第一搭接点存在一级故障；在所述第一温度与任一第二温度的温度差值大 于或者等于第二预设阈值，且小于第三预设阈值的情况下，确定所述第一搭接点存在二级故障；在所述第一温度与任一第二温度的温度差值大于或者等于第三预设阈值的情况下，确定所述第一搭接点存在三级故障。
在所述一级故障的风险等级大于所述二级故障的风险等级，所述二级故障的风险等级大于所述三级故障的风险等级的情况下，根据以下方式确定第一搭接点的故障预测信息：在所述第一温度与任一第二温度的温度差值大于第一预设阈值，且小于第二预设阈值的情况下，确定所述第一搭接点存在三级故障；在所述第一温度与任一第二温度的温度差值大于或者等于第二预设阈值，且小于第三预设阈值的情况下，确定所述第一搭接点存在二级故障；在所述第一温度与任一第二温度的温度差值大于或者等于第三预设阈值的情况下，确定所述第一搭接点存在一级故障。
可以理解的是，将第一温度与第二温度代入诊断模型中进行比较，从而确定故障预测信息，诊断模型表示的是第一温度与多个第二温度之间的函数关系式，是设备运行正常条件下的第一温度与第二温度通过最小二乘法计算出误差最小的回归模型，由于第一温度与第二温度的强相关性，二次回归模型即可满足误差要求。例如，某个搭接点位置的回归模型如下：T＝k(a1[X1]^2+b1X1+c1)；T＝k(a2[X2]^2+b2X2+c2)；T＝k(a3[X3]^2+b3X3+c3)……T＝k(an[Xn]^2+bnXn+cn)，T表示搭接点温度值；X1、X2、X3……Xn分别表示电流、电压、负载率等设置为故障诊断的电参数；a1、b1、c1、a2、b2、c2、a3、b3、c3……an、bn、cn表示各个电参数的回归模型中的变量系数；k表示诊断模型的相关系数，可以根据海拔、环境温度、设备运行时长进行修正。在确定所述第一搭接点的故障预测信息时，将各个电参数值代入到对应的回归模型中计算出理论温度值(相当于上述实施例中的第二温度)，只要第一温度值不满足任何一个计算出的理论温度值的范围，确定第一搭接点存在故障。
进一步的，本公开实施例中的电参数为实时获取到的电参数，第一温度为实时获取到的温度值，根据实时电参数确定对应的实时理论温度值，将实时理论温度值与实时温度值的差值确定第一搭接点的故障预测信息，因此，通过本公开实施例，可以实时确定电源设备的搭接点是否存在故障，进而提高电源设备的安全性。
举例来讲，第一预设阈值为5℃，第二预设阈值为10℃，第三预设阈值为20℃，则第一温度与任一第二温度的温度差值大于5℃，且小于10℃的情况下，确定所述第一搭接点存在一级故障；在所述第一温度与任一第二温度的温度差值大于或者等于10℃，且小于20℃的情况下，确定所述第一搭接点存在二级故障；在所述第一温度与任一第二温度的温度差值大于或者等于20℃的情况下，确定所述第一搭接点存在三级故障。需要说明的是，本公开实施例对上述第一预设阈值、第二预设阈值、第三预设阈值的具体数值不作限定。
2)确定所述第一搭接点对应的分组，其中，同一分组中的搭接点对应的设备单元的类型一致；确定所述分组中的第二搭接点的平均温度，并确定所述第一温度与平均温度的温度差值，其中，所述第二搭接点为所述分组中除所述第一搭接点之外的其他搭接点；根据所述第一温度与所述平均温度的温度差值确定所述第一搭接点的故障预测信息。
可选地，在所述一级故障的风险等级小于所述二级故障的风险等级，所述二级故障的风险等级小于所述三级故障的风险等级的情况下，根据以下方式确定第一搭接点的故障预测信息：在所述第一温度与所述平均温度的温度差值大于第一预设阈值，且小于第二预设阈值的情况下，确定所述第一搭接点存在一级故障；在所述第一温度与所述平均温度的温度差值大 于或者等于第二预设阈值，且小于第三预设阈值的情况下，确定所述第一搭接点存在二级故障；在所述第一温度与所述平均温度的温度差值大于或者等于第三预设阈值的情况下，确定所述第一搭接点存在三级故障。
在所述一级故障的风险等级大于所述二级故障的风险等级，所述二级故障的风险等级大于所述三级故障的风险等级的情况下，根据以下方式确定第一搭接点的故障预测信息：在所述第一温度与所述平均温度的温度差值大于第一预设阈值，且小于第二预设阈值的情况下，确定所述第一搭接点存在三级故障；在所述第一温度与所述平均温度的温度差值大于或者等于第二预设阈值，且小于第三预设阈值的情况下，确定所述第一搭接点存在二级故障；在所述第一温度与所述平均温度的温度差值大于或者等于第三预设阈值的情况下，确定所述第一搭接点存在一级故障。
可以理解的是，当设备正常运行的情况下，属于同组搭接点位置的温度值基本接近，因此某个搭接点位置的第一温度与平均温度的差值过大，说明该搭接点位置存在故障。例如，将相同位置的搭接点分为一组，相同位置的搭接点的温度值分别为T1、T2、T3……Tn，在设备正常工作时，相同位置的搭接点的温度值理论上也是一致的，即T1≈T2≈T3≈……≈Tn，如果发现了某个搭接点位置的温度值T1与其他整流器温度值的平均值(T2+T3+……+Tn)/(n-1)相差过大，说明该搭接点位置存在故障。
可以理解的是，例如，第一预设阈值为5℃，第二预设阈值为10℃，第三预设阈值为20℃，在所述第一温度与所述平均温度的温度差值大于5℃，且小于10℃的情况下，确定所述第一搭接点存在一级故障；在所述第一温度与所述平均温度的温度差值大于或者等于10℃，且小于20℃的情况下，确定所述第一搭接点存在二级故障；在所述第一温度与所述平均温度的温度差值大于或者等于20℃的情况下，确定所述第一搭接点存在三级故障。需要说明的是，本公开实施例对上述第一预设阈值、第二预设阈值、第三预设阈值的具体数值不作限定。
可选的，上述步骤S206可以通过以下方式实现：在所述故障预测信息指示所述第一搭接点存在一级故障的情况下，控制所述电源设备的告警模块发出告警信息；在所述故障预测信息指示所述第一搭接点存在二级故障或者三级故障的情况下，确定所述第一搭接点的位置区域；根据所述位置区域和所述故障预测信息调整所述电源设备的工作状态。
通过以下方式之一控制所述电源设备的告警模块发出告警信息：1)控制所述电源设备的告警模块发送告警提示音；2)控制所述电源设备的告警模块的显示组件显示告警提示灯。
可选的，根据所述位置区域和所述故障预测信息调整所述电源设备的工作状态，包括：在所述第一搭接点位于第一区域或者第三区域或者第七区域，且所述故障预测信息指示所述第一搭接点存在二级故障的情况下，禁止通过所述电源设备的整流器对第一负载设备进行供电，以及控制通过直流电源单元对所述第一负载设备进行供电，其中，所述第一区域为所述电源设备的交流电源单元到与所述交流电源单元连接的断路器的供电线路，所述第三区域为所述电源设备的监测单元到所述电源设备的交流母排的供电线路，所述第七区域为所述电源设备的直流母排到负载断路器以及所述直流母排到电池断路器之间的供电线路对应的区域，所述负载断路器为与所述电源设备对应的负载设备连接的断路器，所述电池断路器为与所述直流电源单元连接的断路器；在所述第一搭接点位于所述第一区域或者第三区域或者第七区域，且所述故障预测信息指示所述第一搭接点存在三级故障的情况下，控制所述断路器断开，以及控制通过所述直流电源单元对所述电源设备对应的第二负载设备进行供电，其中，所述 第二负载设备至少包括：所述第一负载设备。

为了更好的理解上述运行时长的确定方法的过程，以下再结合可选实施例对上述运行时长的确定方法的实现流程进行说明，但不用于限定本公开实施例的技术方案。
如图3是根据本公开实施例的高压直流温度预警智能控制系统的系统框图，如图3所示，系统框图主要包括数据采集单元、故障诊断单元、智能保护单元。
数据采集单元，设置为采集高压直流设备上多个重要位置搭接点的温度和电参数并上传至故障诊断单元。
故障诊断单元，设置为将接收到的温度、电参数数据通过算法分析进行故障风险点预测，根据预测结果下发告警给智能保护单元。
智能保护单元，设置为根据告警信息提示运维人员去现场对设备的具体故障位置进行检查和维护，对于预测结果为恶性故障风险点，智能保护单元还会根据风险点位置自动调节设备的工作状态对设备进行智能保护。
在一个可选的实施例中，温度预警控制系统主要包括数据采集单元、故障诊断单元、智能保护单元三个部分实现，需要具备CAN、RS485、RS232、RS422、网口等通信接口，处理器芯片需满足运算要求，硬件上需要预留一定的数据存储空间。
在一个可选的实施例中，数据采集单元主要采集高压直流设备上多个重要位置搭接点的温度和电参数并上传至故障诊断单元。
1)温度采集可以采用铂电阻、NTC、PTC、热电偶、光纤等传感器测量电路方案实现；
2)电参数包括：电压、电流、功率、负载率、谐波、频率、功率因数等，可以通过电流传感器配合模拟量检测电路实现电参数采集，也可以通过具有通讯功能的电表进行电参数采集；
3)需要采集数据的搭接点位置覆盖高压直流电源柜的各个空间区域，特别是故障率高的搭接点位置，例如，整流器的输入输出端，电池与电池之间的搭接位置，负载接线与铜排的搭接点，铜排与电池接线的搭接点，以及并柜铜排的搭接处。
在一个可选的实施例中，故障诊断单元把接收到的搭接点温度、电参数通过算法分析进行故障预测，根据预测结果下发告警给智能保护单元。
1)故障诊断单元主要通过对比分析法进行故障诊断，本公开实施例给出了两种对比分析方法，在通过其中一种对比分析方法确认所述高压直流电源柜存在故障的情况下，确定所述高压直流电源柜存在故障：
方式一：将接收的温度、电参数数据代入诊断模型中进行对比分析，从而判断出异常温度值；诊断模型表示的是搭接点温度与多个电参数之间的函数关系式，是设备运行正常条件下(无故障)的搭接点温度和电参数数据(出厂测试数据)通过最小二乘法计算出误差最小的回归模型，由于温度和电参数的强相关性，二次回归模型即可满足误差要求；例如某个搭接点位置的回归模型如下：
T＝k(a1X12+b1X1+c1)；
T＝k(a2X22+b2X2+c2)；
T＝k(a3X32+b3X3+c3)；
……
T＝k(anXn2+bnXn+cn)；
T表示搭接点温度值；X1、X2、X3、、、Xn分别表示电流、电压、负载率等设置为故障诊断的电参数；a1、b1、c1、a2、b2、c2、a3、b3、c3……an、bn、cn表示各个电参数的回归模型中的变量系数；k表示诊断模型的相关系数，可以根据海拔、环境温度、设备运行时长进行修正。
在进行对比分析时，各个实时电参数值都会代入到对应的回归模型中计算出理论温度值，只要实时温度值不满足任何一个回归模型计算出的理论温度值范围，确定高压直流电源柜存在故障风险。
方式二：将高压直流电源柜上的搭接点位置进行分组，设备正常运行情况下属于同组搭接点位置的温度值基本接近，诊断模型也是一样的，通过对同组内搭接点位置的温度数据进行对比分析来判断异常搭接点位置。
例如高压直流电源柜各个整流器相同位置的搭接点可分为一组，实时温度值分别为T1、T2、T3……Tn，在设备正常工作时，各个整流器的带载情况一致，温度值理论上也是一致的，即T1≈T2≈T3≈……≈Tn，如果发现了某个整流器的某个搭接点位置的温度值T1与其他整流器温度值的平均值相差过大，说明该整流器对应的搭接点位置存在故障。
2)对各个搭接点位置进行编号，并且根据搭接点位置的特征对搭接点进行分组，然后循环地采集各个搭接点位置的电参数和温度数据，与位置号进行对应，然后代入到对应的诊断模型进行对比分析，根据实时温度值与理论温度值的差值来预测搭接点是否存在故障风险；与此同时，同组搭接点位置之间的温度值也在进行对比分析，筛选出同组位置搭接点中的异常温度值；然后根据预设的判断逻辑，预测出异常温度值对应的搭接点的故障风险程度，并下发告警以及对应的搭接点位置号到智能保护单元做进一步处理。
故障判断逻辑参考表1，T0表示M位置搭接点实时温度值；T1表示M位置搭接点在无故障情况下的理论温度值，是通过某个实时电参数值代入对应的诊断模型计算得到的；T2表示M位置同组其他搭接点的实时温度值的平均值；
表1故障分析判断逻辑
在一个可选的实施例中，智能保护单元接收到故障诊断单元下发的告警信息以及风险点位置号后将会立即提示运维人员去温度异常位置进行检查和维护。对于预测结果为一级、二级恶性故障风险点(相当于本公开的二级故障、三级故障)，智能保护单元还会根据风险点位置自动调节设备的工作状态对设备进行智能保护。
1)智能保护单元自动调节设备的功能可以设置为开启或者关闭，开启后智能保护单元才会自动调节高压直流电源柜的运行状态来规避风险；
2)智能保护单元把高压直流电源柜的搭接点按区域划分管理，图4是根据本公开实施例的高压直流电源柜典型配置框图，一共分了A、B、C、D、E、F、G、H共八个搭接点区域，同一个区域的搭接点的智能保护策略相同。A区域的搭接点主要为市电输入到ATS(自动转换开关)或者断路器的供电线路搭接点；B区域的搭接点为是交流输出母排供电线路搭 接点；C区域的搭接点为交流母排到各整流器断路器供电线路搭接点；D区域的搭接点为整流器断路器到整流器输入端子之间的供电线路搭接点；E区域的搭接点为各个整流器输出端子到直流母排之间的供电线路搭接点；F区域的搭接点为直流母排到负载断路器以及电池断路器之间的供电线路搭接点；G区域的搭接点为电池断路器到电池之间的供电线路搭接点；H区域的搭接点为负载断路器到负载之间的供电线路搭接点；
3)当智能保护单元接收到故障诊断单元下发的一级、二级恶性故障风险点告警以及风险点位置号后，将会把风险点位置号匹配到上述的八个区域，然后根据对应区域的智能保护策略启动相应的保护措施；
4)智能保护的策略主要是通过调节高压直流设备无故障位置的工作状态来分担故障位置的载流量，从而降低故障点的温度，降低风险；调节方式一般有两种，第一种是可以通过通讯总线来控制整流器输出进行电压、电流、工作状态等调节，另一种方式是通过控制搭接点位置对应的断路器断开来进行调节；对于一级恶性故障风险点，主要通过降低该位置的载流量的方式进行调节，进而降低搭接点温度；对于二级恶性故障风险点，由于温度超标太大，风险程度高，因此通过断开该位置的供电线路的方式进行调节，起到隔绝故障的作用；
5)高压直流电源柜各个区域智能保护功能具体实施策略详见表2；
表2、智能保护策略

本公开实施例中通过温度预警的方式有效识别高压直流电源柜设备的故障风险，把风险扼杀在萌芽阶段，并且配有智能保护功能，风险较大时会自动采取措施保护设备，防止人工响应不及时导致故障蔓延，有效解决恶性故障发生的问题，从而提升高压直流设备的可靠性。
