本发明公开一种电能信息处理方法，应用于光伏空调系统中的空调主机系统，光伏空调系统还包括光伏发电系统和群控系统，其中群控系统包括群控终端。基于本发明公开的电能信息处理方法，使得空调主机系统能够获取到高精度的电能信息，从而降低后续控制操作出现偏差的概率，另外，空调主机系统后续能够确定更准确的系统运行数据。
参见图1，图1为本发明公开的一种电能信息处理方法的流程图。该信息处理方法包括：
步骤S11：接收群控终端发送的电能信息。
光伏空调系统中设置有用于为空调主机系统供电的配电单元，以及与配电单元电连接的配电计量电表，群控系统中的群控终端与各个配电计量电表连接。群控终端采集配电计量电表的电能数据，对采集到的电能数据进行预处理获得电能信息，之后将获得的电能信息向空调主机系统发送。也就是说，空调主机系统从群控终端接收到的电能信息，是由群控终端利用配电计量电表的电能数据获得的。由于配电计量电表的精度较高，因此群控终端向空调主机系统发送的电能信息也具有较高精度。
这里需要说明的是，群控终端可以按照预设的时间间隔向空调主机系统发送电能信息，也可以在接收到空调主机系统的数据请求后，响应该数据请求向空调主机系统发送电能信息。
步骤S12：利用接收到的电能信息更新存储于第一存储空间内的电能信息。
空调主机系统接收到群控终端发送的电能信息后，利用接收到的电能信息更新存储于第一存储空间内的电能信息，使得存储于第一存储空间内的电能信息为高精度的电能信息。空调主机系统利用第一存储空间内的电能信息进行控制的过程中，可以降低出现偏差的概率。另外，空调主机系统利用第一存储空间内的电能信息计算系统运行数据过程中，由于使用的是高精度的电能信息，因此空调主机系统能够获得更准确的系统运行数据。
本发明公开的电能信息处理方法，应用于空调主机系统，在接收到群控终端发送的高精度的电能信息后，利用接收到的电能信息更新存储于第一存储空间内的电能信息。基于本发明公开的电能信息处理方法，保证了空调主机系统能够获取到高精度的电能信息，从而降低了后续控制操作过程中出现偏差的概率，另外，由于空调主机系统后续计算系统运行数据过程中使用的是高精度的电能信息，因此空调主机系统能够确定更准确的系统运行数据。
在图1所示电能信息处理方法的基础上，还可以包括以下步骤：在接收群控终端发送的电能信息的同时或之后，接收机载变流器发送的电能信息；在接收机载变流器发送的电能信息之后，将接收到的机载变流器发送的电能信息以及接收时间存储于第二存储空间。
在光伏空调系统运行过程中，空调主机系统不仅接收群控终端发送的高精度的电能信息，也接收机载变流器发送的精度较低的电能信息，并将从机载变流器接收到的电能信息以及该电能信息的接收时间存储于第二存储空间。当空调主机系统和群控系统之间的通信连接中断时，空调主机系统可以利用机载变流器发送的电能信息执行后续控制过程，不会出现控制异常。
作为优选方案，空调主机系统在接收到群控终端发送的电能信息后，还可以将接收到的群控终端发送的电能信息以及接收时间存储于第三存储空间。当光伏空调系统出现运行故障时，可以通过查看空调主机系统中存储的由群控终端发送的电能信息，判断故障是否是由数据传输故障造成的，并且可以根据存储的接收时间确定故障发生的时间。
参见图2，图2为本发明公开的另一种电能信息处理方法的流程图。该电能信息处理方法包括：
步骤S21：接收群控终端发送的电能信息。
步骤S22：将接收到的群控终端发送的电能信息以及接收时间存储于第三存储空间。
步骤S23：利用接收到的群控终端发送的电能信息更新存储于第一存储空间内的电能信息。
步骤S24：接收机载变流器发送的电能信息。
步骤S25：将接收到的机载变流器发送的电能信息以及接收时间存储于第二存储空间。
这里需要说明的是，步骤S21-步骤S23以及步骤S24-步骤S25为并行执行的操作，其执行的时间由接收到电能信息的时间决定。
步骤S26：在空调主机系统和群控系统的通信连接中断的情况下，利用最近一次从群控终端接收到的电能信息以及从机载变流器接收到的电能信息，计算当前时刻的电能信息。
在空调主机系统和群控系统的通信连接中断的情况下，可以将最近一次从群控终端接收到的电能信息作为基准，结合机载变流器发送的电能信息确定光伏空调系统的电能信息。
在电能信息为电量信息的情况下，利用最近一次从群控终端接收到的电能信息以及从机载变流器接收到的电能信息，计算当前时刻的电能信息包括：
获取最近一次从群控终端接收到的第一电量信息，确定从群控终端接收到该第一电量信息的第一时刻；获取从机载变流器接收到的第二电量信息和第三电量信息，确定从机载变流器接收到第二电量信息的第二时刻，确定从机载变流器接收到第三电量信息的第三时刻，计算第二时刻和第三时刻之间的时间间隔；计算第一电量信息和第二电量信息之间的差值，该差值与上述时间间隔的比值为单位时间内的电量信息；计算单位时间内的电量信息和第一时刻距离当前时刻的时间间隔的乘积，该乘积与第一电量信息之和即为当前时刻的电量信息。
这里需要说明的是，电量信息可以是光伏发电系统的发电量信息，也可以是空调主机系统的用电量信息。
步骤S27：利用计算得到的电能信息更新存储于第一存储空间内的电能信息。
