具体实施方式
现将详细参照本公开的实施例，所述实施例的示例在附图中示出，其中，相同的标号始终指的是相同的部件。以下将通过参照附图来说明所述实施例，以便解释本公开。
图2示出根据本公开示例性实施例的风电场的一次调频控制方法的流程图。这里，所述风电场中包括多类机组(即，风力发电机组)。
参照图2，在步骤S10，确定分别与所述多类机组中的每类机组对应的各个一次调频控制线程是否需要启动。
这里，所述一次调频控制线程用于控制包括机组在内的设备针对一个并网点进行一次调频；不同类机组所对应的一次调频控制线程不同。换言之，分别针对每类机组，为其单独配置针对该类机组的至少一个调频控制线程，例如，所述至少一个调频控制线程可由与该类机组对应的一次调频控制应用程序所控制。作为示例，每类机组所对应的各个一次调频控制线程与风电场的各个并网点一一对应。例如，风电场具有N个并网点，每类机组可各自对应N个一次调频控制线程，所述N个一次调频控制线程中的每个用于控制该类机组针对一个并网点进行一次调频控制，所述N个一次调频控制线程中的不同一次调频控制线程用于针对不同并网点进行一次调频控制，从而，当风电场有多个并网点时，无需针对单线程进行拆分，通过多线程并行独立执行，执行效率高且整体逻辑清晰明了。
作为示例，所述包括机组在内的设备除包括机组之外，还可包括其他能够支持针对并网点进行一次调频的设备，本公开对此不作限制。
作为示例，同一厂家生产的风力发电机组可为同一类机组；或者，同一机型的风力发电机组可为同一类机组。应该理解，也可通过其他适当的划分方式，来将风电场的风力发电机组划分为各类，本公开对此不作限制。
作为示例，可确定每个一次调频控制线程所针对的并网点的一次调频支持信息是否满足预设条件；当满足预设条件时，确定该一次调频控制线程需要启动；当不满足预设条件时，确定该一次调频控制线程不需要启动。
作为示例，所述一次调频支持信息可包括：该一次调频控制线程所能够控制的有效机组的数量、所对应的有效AGC设备(有功频率控制设备)的数量、所针对的并网点是否有效。作为示例，可通过配置文件来获取所述一次调频支持信息。一次调频控制线程所对应的AGC设备即与该调频控制线程具有协同控制关系的AGC设备。
相应地，作为示例，所述预设条件可包括：该一次调频控制线程所能够控制的有效机组的数量大于0、所对应的有效AGC设备的数量大于0、所针对的并网点有效。
此外，作为示例，当与任意一类机组对应的各个一次调频控制线程都不需要启动时，启动预先指定的与该类机组对应的一次调频控制线程中的一个默认线程。
在步骤S20，启动需要启动的一次调频控制线程，其中，所启动的一次 调频控制线程占用相应的一组硬压板和指示灯。其中，不同类机组所对应的一次调频控制线程占用不同组的硬压板和指示灯。
应该理解，一组硬压板和指示灯可包括至少一个硬压板和至少一个指示灯。所述硬压板用于接收用户对一次调频相关功能的设置指令，换言之，用户通过对硬压板进行操作，能够对与该硬压板对应的一次调频控制线程所针对的一次调频的相关功能进行开启或关闭。作为示例，所述一次调频相关功能可包括但不限于以下项之中的至少一项：一次调频功能、惯量功能、报错功能。
所述指示灯的点亮状态和熄灭状态用于指示一次调频相关状态，换言之，用户通过该指示灯，能够及时获知与该指示灯对应的一次调频控制线程所针对的一次调频的相关状态。作为示例，所述一次调频相关状态可包括但不限于以下项之中的至少一项：一次调频是否正常。
所述一次调频控制线程用于控制包括机组在内的设备针对一个并网点进行一次调频。具体地，响应于通过所占用的硬压板接收到的用户对一次调频相关功能的设置指令，基于并网点的频率信息，对其所能够控制的包括机组在内的设备进行一次调频控制；并基于当前的一次调频状态，控制所占用的指示灯的状态。
一次调频控制应用程序采用多线程的方式来实现，是考虑到有些电场是两个或更多个并网点，电网考核是按照并网点分别考核，当采用单线程时，遇到单并网点则没有问题，当遇到两个并网点时，在单线程中拆分比较麻烦，且控制效率低，采用多线程(例如，两线程)分别独立并行执行，既让程序逻辑清晰明了，执行效率又高，因此采用此方法。但是，本公开考虑到风电场内可能包括多类机组的情况，例如，为了避免出现下述问题：当风电场包括多类机组时，例如，第一类机组和第二类机组，两类机组由不同厂家生产，两类机组都由风电场场站控制系统统一控制运行，但风电场场站控制系统针对一次调频功能仅设置有两组硬压板和指示灯，无论这两类机组是否经过同一个并网点接入电网，在使用这两组硬压板和指示灯时都会发生冲突。一次调频控制应用程序默认初始化会判断一些必要信息如：有效机组数量、有效AGC设备、有效并网点，都满足要求会给出信息提示，只要有一组数据同时满足具备有效机组、有效AGC设备、有效并网点这三个条件，就会启动一次调频控制应用程序进程，此进程默认开启两个线程，默认两个并网点，当某 个并网点不满足要求时，将总开关关闭，功能不会投入，但是当某个现场的设定值不满足要求时，就会点亮相应的某些指示故障的指示灯，这个关闭开关和点亮故障指示灯的操作是在两个并网点线程启动后，在各自的线程中判断生效的，比如，第二个线程没有投入总出口，这样第二个线程就会把指示灯灭掉。这样真实的效果就是一个控制程序(第一类机组的一次调频控制应用程序)的两个线程把两组指示灯都占用了。当第二个控制应用程序(第二类机组的一次调频控制应用程序)想要用第二组指示灯时，就会出现两个程序打架的现象。
因此，本公开提出：可针对风电场的一次调频功能，设置多组硬压板和指示灯，以保证不同类机组所对应的一次调频控制线程占用不同组的硬压板和指示灯，即，不同类机组针对一次调频功能使用不同组的硬压板和指示灯。作为示例，硬压板和指示灯的总组数可基于风电场的并网点的总数量和风电场内不同类机组的总类数确定，其中，硬压板和指示灯的总组数与风电场的并网点的总数量呈正相关；硬压板和指示灯的总组数与风电场内不同类机组的总类数呈正相关。
作为示例，步骤S10和步骤S20可由一次调频控制应用程序来执行。作为示例，每类机组可分别对应各自的一次调频控制应用程序，具体地，可分别针对每类机组，为其配置与其一一对应的一次调频控制应用程序，该一次调频控制应用程序可用于与通信层通信，判断为其配置的一次调频控制线程中的哪些需要被启动并启动，即，确定与该类机组对应的各个一次调频控制线程是否需要启动，并启动需要启动的一次调频控制线程的步骤可由与该类机组对应的一次调频控制应用程序来执行。
图3示出根据本公开示例性实施例的一次调频控制应用程序的数据交互的示例。这里，风电场包括第一类机组和第二类机组共两类机组。如图3所示，风电场的场控设备中的一次调频控制设备包括两层：控制层和通信层，控制层设置有第一类机组的一次调频控制应用程序和第二类机组的一次调频控制应用程序，控制层通过控制通信层与第一类机组、第二类机组、与第一类机组对应的AGC设备(或能量管理平台EMP)、与第二类机组对应的AGC设备(或能量管理平台EMP)、测控设备等设备进行通信，完成数据读取和命令写入的任务。控制层与通信层之间存在如下形式的内部数据交互：控制层获取通信层解析处理的生数据，并将计算好的工程量控制命令下发给通信 层，从而完成一个调度周期的处理。作为示例，第一类机组的一次调频控制应用程序和第二类机组的一次调频控制应用程序之间没有数据交互。
作为示例，所述方法可由风电场场站控制系统中的一次调频控制设备来执行，作为示例，可在一次调频控制设备初始化时，执行步骤S10和步骤S20。
应该理解，所启动的一次调频控制线程具体占用哪一组硬压板和指示灯可由一次调频控制线程确定，例如，所启动的一次调频控制线程会执行具体的判断策略来确定所占用的硬压板和指示灯，或可由对应的一次调频控制应用程序执行具体的判断策略确定后再对一次调频控制线程进行配置，以使一次调频控制线程根据配置信息确定其所占用的硬压板和指示灯，此外，所启动的一次调频控制线程也会循环执行具体的一次调频控制策略。将在下面的实施例中描述判断策略的具体示例。
作为示例，可当所启动的一次调频控制线程所对应的一类机组与其他类机组共同通过该一次调频控制线程所针对的并网点接入电网时，该一次调频控制线程占用排序与该类机组的优先级相应的一组硬压板和指示灯；当所启动的一次调频控制线程所对应的一类机组单独(即，不与其他类机组共同)通过该一次调频控制线程所针对的并网点接入电网时，该一次调频控制线程占用排序与所通过的并网点的优先级相应的一组硬压板和指示灯。具体说来，各组硬压板和指示灯有其排序，例如，可按各组硬压板和指示灯的实际设置位置对各组硬压板和指示灯进行排序，例如，可按从上到下的实际设置位置对各组进行排序，优先级越高，与其相应的一组硬压板和指示灯的排序越靠前。
以所述风电场包括第一类机组和第二类机组，所述风电场通过一个并网点接入电网，所述风电场的场控设备上设置有第一组硬压板和指示灯、以及第二组硬压板和指示灯为例，可当所启动的一次调频控制线程用于控制第一类机组针对并网点进行一次调频时，该一次调频控制线程占用第一组硬压板和指示灯；当所启动的一次调频控制线程用于控制第二类机组针对并网点进行一次调频时，该一次调频控制线程占用第二组硬压板和指示灯，其中，关于占用硬压板和指示灯，第一类机组的优先级高于第二机组的优先级。
以所述风电场包括两类机组，所述风电场通过第一并网点和第二并网点接入电网，所述风电场的场控设备上设置有第一组硬压板和指示灯、以及第二组硬压板和指示灯为例，可当所启动的一次调频控制线程用于控制一类机 组针对第一并网点进行一次调频，且仅所述一类机组通过第一并网点接入电网时，该一次调频控制线程占用第一组硬压板和指示灯；当所启动的一次调频控制线程用于控制另一类机组针对第二并网点进行一次调频，且仅所述另一类机组通过第二并网点接入电网时，该一次调频控制线程占用第二组硬压板和指示灯，其中，关于占用硬压板和指示灯，第一并网点的优先级高于第二并网点的优先级。
作为示例，与每类机组对应的一次调频控制应用程序可通过全双工通信协议与测控设备进行通信，其中，所述测控设备用于采集风电场的各个并网点的频率信息。此外，所述测控设备还可用于采集硬压板的动作信息，接收用于控制指示灯的指令并控制指示灯的点亮和熄灭。根据本公开的示例性实施例，能够避免当风电场包括多类机组时，与所述多类机组对应的多个一次调频控制应用程序通过通信层与测控设备通信时的数据读取效率。
作为示例，可与每类机组对应的一次调频控制应用程序通过寄存器方式实现与测控设备之间的数据读写，而非在读写数据时使用系数处理方式，从而提高了数据读写效率。具体说来，当待写数据的数据类型是数字量而非模拟量时，直接将待写数据中值为0的字节填充为00，值为1的字节填充为FF00，并将处理完的待写数据写入待发送的命令报文结构体中；当待读数据的数据类型是数字量而非模拟量时，可按照下述方式来按位取数据：把传进来的结构体属性中的系数位当作移位所需的位数，将传进来的数据值移位所述位数后，再和0x01作“与”操作，就得到该数据值的数据量数据。
图4示出根据本公开示例性实施例的启动一次调频控制线程的方法的示例。所述方法可由一类机组的一次调频控制应用程序执行，所述一次调频控制应用程序管理两个一次调频控制线程(以下，也称为线程1和线程2)，每个线程分别对应一个并网点。
参照图4，在步骤S101，针对两个备用的一次调频控制线程获取所有数据。具体地，分别为两个线程从通信层读取所有的生数据，后续的控制模型数据都由生数据模型生成。由于两个一次调频控制线程暂未确定哪个需要启动，这里称为备用线程。
在步骤S102，进行频率初始化。作为示例，可按照设计好的低频和过频典型曲线数据文件，获取典型曲线扰动测试模拟频率数据集，为测试实际执行情况做数据备用。
在步骤S103，判断样板机及与样板机相对应的机组。这里，样板机为调度规定不可控机组，且不同机组要跟着样板机功率趋势执行，因此这里要判断哪些是样板机，以及，哪些机组根据哪台样板机的功率趋势执行。
在步骤S104，获取所有句柄。句柄则是指一次调频控制应用程序的控制模型与生数据模型相关联的纽带。
在步骤S105，检查并网点设置信息。作为示例，可根据设计好的并网点1和2的配置名称，分别获取两个并网点的变压器序号，并判断两个变压器序号是否一样或无效，当正确时变压器序号分别设置给两个一次调频控制线程的并网点序号变量中。
在步骤S106，获取有效机组信息和有效AGC设备信息。有效则表示控制中需要的控制模型数据，一定能获取到对应的生数据模型数据。即机组规定了一次调频控制中必须的变量，从这些变量名能找到对应的句柄，则表示有效；AGC设备规定了一次调频控制中必须的变量，从这些变量名能找到对应的句柄，则表示有效。
在步骤S107，计算与每个线程相关联的机组总的额定功率。每个机组都标记了挂载在哪个变压器序号下，根据变压器序号，线程序号与变压器序号的关系可以得到，即，机组可以跟线程序号相对应起来，每个线程下的所有机组的最大功率总和，即为线程额定功率。
在步骤S108，判断线程启动条件。
具体地，在步骤S201，当确定根据线程1结构体中有效机组数量不为0，有效AGC设备数量不为0，并网点正确时，确定线程1有效，在步骤S202，将线程1的启动条件G_th1置位1；在步骤S203，当确定根据线程2结构体中有效机组数量不为0，有效AGC设备数量不为0，并网点正确时，确定线程2有效；在步骤S204，将线程2的启动条件G_th2置位1；在步骤S205，当确定线程1和线程2均无效时，默然将G_th1置位1。
在步骤S109，创建线程。作为示例，可由线程启动判断标志和线程启动后的线程号，创建线程。
具体地，在步骤S301，当G_th1为1时，创建线程1；在步骤S302，当G_th2为1时，创建线程2。
