具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请提供的火电机组启动方法，可以应用于如图1所示的应用环境中。其中，终端102通过网络与火电机组104中的各个系统和设备进行通信。终端102可以向火电机组发送启动指令，从而终端102可以启动火电机组104中的基础系统，并在基础系统启动完成时，获取火电机组104中辅助蒸汽系统对应的预设蒸汽汽源并确定火电机组中的多个待启动的辅机系统，再基于预设蒸汽汽源和基础系统的运行信息，向火电机组104中符合条件的辅机系统发送启动指令，以启动符合启动条件的辅机系统，终端102在基于已启动的辅机系统的运行信息符合其他待启动的辅机系统对应的启动条件时，可以向该其他待启动的辅机系统发送启动指令，以启动该其他待启动的辅机系统，直到火电机组中的多个待启动的辅机系统均启动完成。其中，终端102可以但不限于是各种工业控制计算机、个人计算机、笔记本电脑、智能手机和平板电脑。
在一个实施例中，如图2所示，提供了一种火电机组启动方法，以该方法应用于图1中的终端为例进行说明，包括以下步骤：
步骤S202，响应于针对待启动的火电机组104的启动指令，启动火电机组104中的基础系统。
其中，火电机组104可以是用于进行火力发电的机组，火电机组104中可以设置有多个系统和设备，例如除盐水系统、凝结水系统、辅助蒸汽系统等。火电机组104在进行正常发电工作前，需要首先启动其中的各个系统。终端102可以接收针对待启动的火电机组104的启动指令，例如工作人员通过终端102触发启动指令。则终端102可以响应上述启动指令，并首先启动火电机组104中的基础系统。例如，终端102响应针对火电机组的启动指令后，可以先对基础系统发送针对基础系统的启动指令，待基础系统启动完成后再向其他系统发送启动指令。其中，上述基础系统包括循环水系统、开式水系统、空压机系统以及密封油系统等。终端102可以按照特定的顺序启动上述基础系统，例如，上述基础系统中的各个系统的启动条 件可以与其他基础系统的运行信息有关，终端102可以基于基础系统中的每个系统的启动条件，在检测到某个系统的启动条件满足时则启动该系统，实现系统的并行启动。
步骤S204，若检测到基础系统启动完成，获取火电机组104中辅助蒸汽系统对应的预设蒸汽汽源并确定火电机组104的多个待启动的辅机系统；辅机系统有对应的运行信息以及启动条件。
其中，基础系统可以是火电机组104启动前需要提前启动的系统。基础系统是保证火电机组104正常运行的基础。当终端102检测到基础系统启动完成时，终端102可以进行启动辅助蒸汽系统需要的预设蒸汽汽源的获取，以及确定需要启动的火电机组104中的多个待启动的辅机系统，另外终端102还可以设置各系统冗余配置的辅机系统的优先启动权。其中，辅机系统表征火电机组104中在基础系统启动后启动的系统，多个辅机系统均参与到火电机组104的运行中，且每个辅机系统有对应的运行信息和启动条件，每个辅机系统的启动条件与其他辅机系统的运行信息的数值对应，即当一个辅机系统的运行信息达到某个状态时，某个其他的辅机系统的启动条件将因此满足，此时可以将该其他的辅机系统进行启动。终端102可以为火电机组104中的每个系统和设备分别设置对应的监控图标，并使用不同颜色标识设备和系统的状态，例如，终端102可以在机组自动启动监控界面中设置设备预选功能，用于对上述待启动的辅机系统进行选择。设备预选功能用于在机组启动前选择设置各系统冗余配置的辅机系统的优先启动权和辅助蒸汽的汽源选择。未被选择的可用设备图标可以显示为第一颜色，被选择的可用设备图标显示为第二颜色。其中第一颜色和第二颜色不同，对于冗余配置的辅机系统和设备，在运行值班人员未选择的情况下，自动默认选择指定设备为优先启动设备。值班人员可根据实际需要变更上述辅机系统和设备的优先启动权。如果某台辅机系统和设备不可用，该台设备程序自动选择另一台可用设备作为优先启动设备，不可用设备的图标显示为第三颜色。如果冗余配置的系统和设备均不可用，则无法选择优先启动设备，该设备相关的系统被禁止启动。
上述火电机组104中的预设蒸汽汽源可以有多个，终端102需要选择辅助蒸汽系统需要的预设蒸汽汽源，例如，在一个实施例中，获取火电机组104中辅助蒸汽系统对应的预设蒸汽汽源，包括：获取火电机组104中辅助蒸汽系统对应的预设蒸汽汽源；预设蒸汽汽源包括以下至少一种：启动锅炉、相邻机组以及本机余汽。本实施例中，火电机组104中的辅助蒸汽系统可以根据预设蒸汽汽源的选择确定出不同的辅助蒸汽系统，其中预设蒸汽汽源包括启动锅炉、相邻机组和本机余汽中的至少一种，终端102需要首先确定使用的预设蒸汽汽源，例如通过工作人员进行选择，从而终端102根据选择的预设蒸汽汽源启动对应的辅助蒸汽系统。例如，对于辅助蒸汽汽源的选择，每次机组启动前都需要由运行值班人员在启动锅炉、相邻机组、本机余汽三个选项中手动选择，如果汽源未选择，相关系统及机组启动流程将被禁止执行。如果启动锅炉系统不可用，启动锅炉汽源选择图标将被闭锁操作；如果相邻机组辅助蒸汽参数指标不合格且相关设备状态不满足要求，相邻机组汽源选择图标将被闭锁操作；如果本机余汽参数指标不合格且相关设备状态不满足要求，本机余汽汽源选择图标将被闭锁操作。
步骤S206，基于预设蒸汽汽源和基础系统的运行信息，启动多个待启动的辅机系统中符合启动条件的辅机系统。
其中，终端102在启动火电机组104时可以首先启动基础系统和确定启动辅助蒸汽系统所需的预设蒸汽汽源。终端102可以获取预设蒸汽汽源和基础系统的运行信息，并基于这些运行信息启动上述选择的多个待启动的辅机系统中符合条件的辅机系统。例如，终端102根据基础系统的运行信息和设备检测到预设蒸汽汽源已经确定时，确定出待启动的辅机系统中的符合启动条件的辅机系统，并首先启动该辅机系统。其中，火电机组104中的系统启动方式可以包括多种，火电机组104的启动方式包括断点启动、一键启动和功能组启动等方式。对于断点启动，终端102可以将一个完整的燃气-蒸汽联合循环机组，即上述火电机组104的启动过程分为四个断点，分别为系统准备断点、锅炉上水断点、燃气轮机启动并网断点和汽轮机升温升压断点。其中，系统准备断点涉及的系统包括循环水系统、开式水系统、空压机系统、密封油系统、除盐水系统、凝结水系统、启动锅炉系统、辅助蒸汽系统、轴封系统、抽真空系统。并且终端102可以将上述多个系统分为多个功能组。例如，终端102可以针对循环水系统、开式水系统、密封油系统、除盐水系统、凝结水系统、启动锅炉系统、轴封系统、抽真空系统，分别设置一个功能组。功能组为根据某生产系统工艺要求，依据各种条件判断，自动顺序控制该系统所有相关设备的控制流程。终端102还可以针对辅助蒸汽系统，根据蒸汽来源分别设置汽源来自启动锅炉、汽源来自相邻机组、汽源来自本机余汽的三个 辅助蒸汽系统启动功能组。针对空压机系统，独立设置根据气罐压力变化逐台启动和停止的控制逻辑，不设置功能组。终端102可以为锅炉上水断点设置低压汽包上水、中压汽包上水、高压汽包上水和低压省煤器再循环系统启动等若干功能组；在燃气轮机启动并网断点设置燃气轮机启动并网一个功能组；以及在汽轮机升温升压断点设置低压主蒸汽升温升压、中压主蒸汽升温升压、高压主蒸汽升温升压等若干功能组。
其中，断点启动可以是将火电机组104中的多个系统分为多个断点，在每个断点中进行系统的启动，到达一个断点时，需要确认操作才进行下一断点的启动；一键启动可以是在启动指令触发时，火电机组104直接启动直到启动完成；功能组启动可以是将上述火电机组104中的多个系统按照功能进行分组并依照每个功能组进行启动。另外，终端102可以为每个功能组均设置功能组启动界面。当选择功能组启动模式时，值班人员只能在功能组启动界面上操作启动，断点启动界面和机组一键启动界面中启动按钮被闭锁。所有功能组均可在功能组启动模式下执行，其中循环水系统、开式水系统和密封油系统功能组只能在功能组启动模式下执行。如果机组处于南方偏热地区，低压省煤器再循环系统功能组可设置仅在功能组启动模式下执行。
终端102可以为上述系统准备断点、锅炉上水断点、燃气轮机启动并网断点和汽轮机升温升压断点分别设置断点启动界面，当选择断点启动模式时，值班人员只能在断点启动界面上操作启动，一键启动界面和功能组启动界面中启动按钮被闭锁。上述火电机组104中的除盐水系统、凝结水系统、启动锅炉系统、辅助蒸汽系统、轴封系统、抽真空系统、低压汽包上水、中压汽包上水、高压汽包上水、燃气轮机启动并网、低压主蒸汽升温升压、中压主蒸汽升温升压、高压主蒸汽升温升压等功能组可在断点启动模式下执行。如果机组处于北方偏寒地区，低压省煤器再循环系统功能组可设置在断点启动模式下执行。终端102的系统准备断点启动流程将根据工艺要求自动跳转执行除盐水系统、凝结水系统、启动锅炉系统、辅助蒸汽系统、轴封系统和抽真空系统启动功能组。终端102的锅炉上水断点启动流程将根据工艺要求自动跳转执行低压汽包上水、中压汽包上水、高压汽包上水功能组，必要时自动执行低压省煤器再循环系统启动功能组。终端102的燃气轮机启动并网断点启动流程将根据工艺要求自动执行燃气轮机启动并网功能组。终端102的汽轮机升温升压断点启动流程将根据工艺要求自动跳转执行低压主蒸汽升温升压、中压主蒸汽升温升压、高压主蒸汽升温升压功能组。
终端102还可以设置机组一键启动界面。当选择机组一键启动模式时，值班人员只能在机组一键启动界面上操作启动，断点启动界面和功能组启动界面中启动按钮被闭锁。能在断点启动模式下执行的功能组均可在机组一键启动模式下执行。终端102的机组一键启动流程将根据工艺要求自动跳转执行系统准备、锅炉上水、燃气轮机启动并网和汽轮机升温升压断点启动流程。在机组启动过程中，终端102的机组启动模式可以从机组一键启动切换至断点启动模式，也可由断点启动模式切换至功能组启动模式。当机组一键启动模式切换至断点启动模式时，当前正在执行的断点流程完成后，终端102将不再往下执行，必须值班人员手动启动后续断点流程再继续执行。当断点启动模式切换至功能组启动模式时，当前正在执行的功能组流程完成后，终端102将不再往下执行，必须值班人员手动启动后续功能组流程再继续执行。
步骤S208，若基于已启动的辅机系统的运行信息确定符合其他待启动的辅机系统对应的启动条件，执行启动其他待启动的辅机系统的流程，直到多个待启动的辅机系统均启动完成。
其中，终端102可以在基础系统已运行后，进行待启动的辅机系统的启动流程。并且终端102可以基于已启动的辅机系统的运行信息检测其他待启动的辅机系统对应的启动条件是否符合，若基于已启动的辅机系统的运行信息确定其他待启动的辅机系统对应的启动条件已满足，则终端102可以执行启动该其他待启动的辅机系统的流程，直到上述选择的多个待启动的辅机系统均启动完成。例如，终端102可以基于基础系统的运行信息首先启动一个辅机系统，并基于该启动的辅机系统的运行信息检测是否符合其他待启动的辅机系统的启动条件，若符合则立即启动该待启动的辅机系统，而不必等待目前正在启动的辅机系统启动完成。
具体地，如图3所示，图3为另一个实施例中火电机组启动方法的流程示意图。在断点启动或机组一键启动模式下，为加快机组启动速度，终端102在机组启动过程每个步骤(功能组或断点)之前，均设置两组判断条件。第一组条件判断该步骤是否执行完成或其流程正在执行中，第二组条件判断该步骤流程启动条件是否已满足。在机组启动流程要执行某个步骤前，先判断第一组条件。若该步骤已执行完成或流程正在执行中，则机组启动流程不再执行该步骤，而直接进行后序步骤条件判断；若该步骤尚未执行，则 机组启动流程判断第二组条件，在该步骤启动条件满足时开始执行该步骤流程。在该步骤流程执行过程中，若后序步骤未执行且其启动条件已满足，机组启动流程不等前序步骤执行完成，立即执行后序步骤，从而有效减少等待前序步骤完成的时间，加快机组启动速度。例如，在机组断点启动模式时，辅助蒸汽系统启动完成的判断条件需要辅助蒸汽温度达到180℃，而其后序轴封系统启动条件只需要辅助蒸汽温度达到170℃，故而在辅助蒸汽温度达到170℃，终端102的机组启动流程不等辅助蒸汽系统启动流程执行完成，立即执行轴封系统启动功能组。再例如，在机组一键启动模式下，锅炉上水断点流程的启动判断条件只需要系统准备断点中的凝结水系统启动运行正常即可，故而在凝结水系统启动运行正常后，机组启动流程不等系统准备断点所有功能组执行完成，立即执行锅炉上水断点流程。
上述火电机组启动方法中，通过首先启动火电机组中的基础系统，若检测到基础系统启动完成，则获取火电机组中辅助蒸汽系统对应的预设蒸汽汽源并确定火电机组中的多个待启动的辅机系统，并基于预设蒸汽汽源和基础系统的运行信息，启动多个待启动的辅机系统中符合启动条件的辅机系统；若基于已启动的辅机系统的运行信息确定符合其他待启动的辅机系统对应的启动条件，则执行启动该其他待启动的辅机系统的流程，直到多个待启动的辅机系统均启动完成。相较于传统的需要启动完成一个系统后再进行下一系统的启动条件判断，本方案通过在每个系统启动的同时检测后序其他待启动系统的启动条件，并在满足时启动对应的其他待启动系统，提高火电机组的启动效率。
在一个实施例中，启动所述火电机组104中的基础系统，包括：启动火电机组104中的循环水系统，以向开式水系统提供水源；检测循环水系统的运行信息，若检测到循环水系统的运行正常信息，启动所述开式水系统，以冷却空压机系统；检测开式水系统的运行信息，若检测到开式水系统的运行正常信息，启动空压机系统，以向火电机组104中的气动阀门提供动力用气以及检修用气；检测空压机系统的运行信息，若检测到空压机系统的运行正常信息，启动密封油系统，以向火电机组104中的发电机提供密封油。
本实施例中，在功能组启动模式下，终端102在启动火电机组104时，可以首先启动火电机组104中的基础系统，其中基础系统包括循环水系统、开式水系统、空压机系统以及密封油系统。终端102可以首先启动火电机组105中的循环水系统，从而循环水系统可以向开式水系统提供水源；终端102启动循环水系统后，可以检测循环水系统的运行信息，若检测到循环水系统运行正常，则启动开式水系统，从而开式水系统可以冷却空压机系统；终端102启动开式水系统后，可以检测开式水系统的运行信息，若检测到开式水系统运行正常，则终端102可以启动空压机系统，从而空压机系统可以向火电机组104中的气动阀门提供动力用气以及检修用气；终端102可以检测空压机系统的运行信息，若检测到空压机系统运行正常，则终端102可以启动密封油系统，从而密封油系统可以向火电机组104中的发电机提供密封油。
其中，终端102可以在“功能组启动”模式下启动上述各个基础系统。例如，在功能组启动模式下，若终端102检测到循环水系统未启动运行，首先值班人员通过功能组设备可用性和启动条件状态显示图标确认该功能组相关设备均可用且启动条件已满足，然后发令使终端102执行循环水系统启动功能组。用于为凝汽器提供冷却水来凝结汽轮机低压缸的排汽，同时为开式冷却水系统提供水源。在循环水系统启动运行正常后，值班人员通过功能组设备可用性和启动条件状态显示图标确认开式水系统启动功能组相关设备均可用且启动条件已满足，然后发令终端102执行开式水系统启动功能组，从而可以用于在循环水系统启动后，为空压机冷却、空气干燥机冷却、润滑油系统冷却器、控制油冷却器、凝结水泵轴承冷却水、真空泵冷却器、发电机氢气干燥器冷却水、发电机密封油冷却器、发电机氢气冷却器、高压给水泵电机冷却、中压给水泵电机冷却、高压给水泵润滑油系统冷却器、汽水取样冷却器等用户提供冷却用水。在开式水系统启动运行正常后，终端102可以检查空压机系统是否启动正常；如果空压机系统未启动，由终端102启动或值班人员手动启动运行并投入自动联动功能，从而可以使空压机系统用于为各种气动阀门提供动力用气和检修用气。在空压机系统运行正常后，值班人员或终端102可以通过功能组设备可用性和启动条件状态显示图标确认密封油系统启动功能组相关设备均可用且启动条件已满足，然后发令使终端102执行密封油系统启动功能组，从而使密封油系统用于在发电机充氢前，向发电机密封瓦提供密封油，保证油压高于发电机内氢压，以防止发电机内氢气沿转轴与密封瓦之间的间隙向外泄漏，同时也防止油压过高而导致发电机内大量进油。
通过本实施例，终端102可以按照特定顺序首先启动火电机组104中的基础系统，从而终端102可以将启动后的基础系统的运行信息作为基础，启动火电机组104中的其他系统，提高了火电机组104的启动 效率。
在一个实施例中，确定火电机组的多个待启动的辅机系统，包括：确定火电机组中的除盐水系统、凝结水系统、启动锅炉系统、汽源来自启动锅炉系统的辅助蒸汽系统、轴封系统、抽真空系统、汽包上水系统、低压省煤器再循环系统、燃气轮机启动并网系统以及主蒸汽升温升压系统，作为多个待启动的辅机系统。
本实施例中，终端102在启动基础系统后，可以设置各系统冗余配置的辅机系统的优先启动权和辅助蒸汽系统的预设蒸汽汽源的选择，并确定待启动的辅机系统。其中，辅助蒸汽系统可以根据选择的蒸汽汽源的不同而选择不同的启动功能组。例如，在循环水系统、开式水系统、空压机系统、密封油系统及其它基础性支持系统启动运行正常后，由值班人员选择辅助蒸汽汽源，确认冗余配置设备，即上述辅机系统的预选情况。若预设蒸汽汽源为启动锅炉，确定辅助蒸汽系统执行汽源为启动锅炉系统的辅助蒸汽系统启动功能组。则本实施例以启动锅炉系统作为辅助蒸汽系统的预设蒸汽汽源为例，终端102可以确定上述火电机组104中的除盐水系统、凝结水系统、启动锅炉系统、汽源来自启动锅炉系统的辅助蒸汽系统、轴封系统、抽真空系统、汽包上水系统、低压省煤器再循环系统、燃气轮机启动并网系统以及主蒸汽升温升压系统，作为多个待启动的辅机系统。则终端102可以将上述选择的待启动的辅机系统按照特定的规则进行启动。
通过本实施例，终端102可以基于蒸汽汽源的不同确定对应的辅助蒸汽系统，从而基于该辅助蒸汽系统以及多个辅机系统确定出需要启动的多个待启动的辅机系统，并按照特定规则进行启动，进而提高了火电机组104的启动效率。

本实施例中，终端102可以在预设蒸汽汽源确定后以及基础系统启动后，监测基础系统的运行信息，并基于这些运行信息启动上述确定的待启动的辅机系统中符合启动条件的辅机系统。例如，终端102在检测到基础系统的运行正常信息以及预设蒸汽汽源已经确定时，确定火电机组104中的除盐水系统为符合启动条件的辅机系统；则终端102可以启动除盐水系统，从而除盐水系统可以向启动锅炉系统提供补给水和除盐冷却水、向凝结水系统提供补给水、向轴封系统提供水封注水、向抽真空系统提供启动注水以及向燃气轮机启动并网系统提供清洗用水。其中，上述基础系统的运行正常信息需要所有基础系统的运行信息均正常，例如，终端102检测到循环水系统的运行正常信息、开式水系统的运行正常信息、空压机系统的运行正常信息以及密封油系统的运行正常信息时，可以确定基础系统运行正常。
终端102还可以利用显示的图标确认辅机系统的启动条件是否满足。例如，值班人员通过终端102中显示的功能组设备可用性和启动条件状态显示图标确认除盐水系统启动功能组相关设备均可用且启动条件已满足，然后发令使终端102执行除盐水系统启动功能组，从而可以使除盐水系统用于为启动锅炉和凝汽器提供补给水，为轴封冷却器提供水封注水，为凝结水泵启动提供密封用水，为真空泵提供启动注水，为燃机清洗水箱供水，也为启动锅炉给水泵和制氢系统提供闭式除盐冷却水。
