燃煤发电机组自启动进程控制方法及装置Coal-fired generating set self-starting process control method and device

技术领域technical field

本申请涉及燃煤发电机技术领域，尤其涉及一种燃煤发电机组自启动进程控制方法及装置。The present application relates to the technical field of coal-fired generators, in particular to a method and device for controlling the self-starting process of a coal-fired generator set.

背景技术Background technique

相关技术中，为实现燃煤发电机组快速启动全自动的功能，机组程序自动启停(Automatic Procedure Start-up/Shut-down，APS)已经在全国各个燃煤发电机组实施并应用，其功能应用的机组包括亚临界、超临界、超超临界机组。其中包括断点一、断点二、断点三、断点四及断点五，在实际电厂生产过程中，运行人员依次手动点击启动各个断点的功能组，来实现燃煤机组启机。断点一为机组准备；断点二为锅炉启动；断点三为汽机冲转；断点四为机组并网；断点五为机组升负荷。其弊端是对燃煤发电机组的启动进程没有清晰的划分，并且需要逐一点击操作各个断点来进行启动，操作过于繁琐，启动方式过于单一。若运行人员想实现断点四机组并网的目标，就必须先启动断点一，再启动断点二，接着完成断点四，才能最终实现断点四。In related technologies, in order to realize the quick start-up and full-automatic function of coal-fired generating sets, the Automatic Procedure Start-up/Shut-down (APS) has been implemented and applied in various coal-fired generating sets across the country. The units include subcritical, supercritical and ultra-supercritical units. These include breakpoint 1, breakpoint 2, breakpoint 3, breakpoint 4 and breakpoint 5. In the actual production process of the power plant, the operating personnel manually click and start the function groups of each breakpoint in order to realize the start-up of the coal-fired unit. Breakpoint 1 is unit preparation; breakpoint 2 is boiler startup; breakpoint 3 is steam turbine running; breakpoint 4 is unit grid connection; breakpoint 5 is unit load increase. The disadvantage is that there is no clear division of the starting process of the coal-fired generating set, and each breakpoint needs to be clicked one by one to start. The operation is too cumbersome and the starting method is too single. If the operator wants to achieve the goal of grid-connected breakpoint four units, he must first start breakpoint one, then start breakpoint two, and then complete breakpoint four before finally realizing breakpoint four.

作为一种可能实施的示例，响应于接收到机组准备进程启动指令、锅炉启动进程启动指令、汽机冲转进程启动指令、机组并网进程启动指令和机组升负荷进程启动指令中的任一指令，根据预设进程启动顺序，即依次启动机组准备进程、锅炉启动进程、汽机冲转进程、机组并网进程和机组升负荷进程，确定启动指令中的目标进程，将排序在目标进程之前的进程确定为预启动进程。As an example of a possible implementation, in response to receiving any one of the instructions for starting the unit preparation process, starting the boiler starting process, starting the turbine rushing process, starting the grid connection process of the unit, and starting the load increase process of the unit, According to the preset process start sequence, that is to start the unit preparation process, the boiler start process, the turbine rush process, the unit grid connection process and the unit load increase process in sequence, determine the target process in the start command, and determine the process prior to the target process for the pre-start process.

举例来说，响应于接收到汽机冲转进程启动指令，按照预设进程启动顺序，确定预启动进程为机组准备进程、锅炉启动进程。For example, in response to receiving the start instruction of the steam turbine running process, according to the preset process start sequence, it is determined that the pre-start process is a unit preparation process and a boiler start process.

Start normally, if the unit preparation process starts normally, obtain the second current operating data corresponding to the boiler starting process, determine whether the boiler starting process is normally started based on the second current operating data, if the boiler starting process starts normally, start the target process, that is Start the steam engine flushing process. If the unit preparation process is not started normally, the unit preparation process, the boiler start process and the steam turbine run-in process are sequentially controlled to start. If the unit preparation process starts normally, but the boiler start-up process does not start normally, the boiler start-up process and the steam turbine run-in process start are sequentially controlled.
