具体实施方式Detailed ways
以下结合附图对本发明实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明实施例，并不用于限制本发明实施例。The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.
图1是本发明一种实施方式提供的降低汽轮机汽阀关闭试验压力波动的方法的流程图，如图1所示，一种降低汽轮机汽阀关闭试验压力波动的方法，所述方法包括：Fig. 1 is the flow chart of the method for reducing the pressure fluctuation of steam turbine steam valve closing test provided by an embodiment of the present invention, as shown in Fig. 1, a kind of method for reducing the pressure fluctuation of steam turbine steam valve closing test, described method comprises:
步骤S101：获取汽阀在关闭试验过程中的主蒸汽压力；Step S101: Obtain the main steam pressure of the steam valve during the closing test;
在本实施例中，该汽轮机配置有2只高压主汽阀、4只高压调阀和2组中压联合阀，高压调阀的阀序为复合配汽方式，四个高压调阀(阀A、阀B、阀C、阀D)的开启顺序为D-BC-A；通常来说，高压调阀在进行关闭实验时，以2％/s的基准速率逐渐关闭至10％后，快速关闭电磁阀动作，安全油压泄去后高压调阀快关，高压调阀全关反馈收到后自动以2％/s的基准速率开启至试验开始前阀位；因此在实验过程中，通过蒸汽压力监测设备采集主蒸汽压力。In this embodiment, the steam turbine is equipped with 2 high-pressure main steam valves, 4 high-pressure regulating valves and 2 sets of medium-pressure combined valves. The valve sequence of the high-pressure regulating valves is a compound steam distribution method. , valve B, valve C, valve D) the opening sequence is D-BC-A; generally speaking, when the high-pressure regulating valve is performing a closing experiment, it is gradually closed to 10% at a reference rate of 2%/s, and then quickly closed The solenoid valve operates, and the high-pressure regulating valve closes quickly after the safety oil pressure is released. After receiving the feedback of the high-pressure regulating valve being fully closed, it automatically opens to the valve position before the test at a reference rate of 2%/s; therefore, during the experiment, through the steam The pressure monitoring equipment collects the main steam pressure.
步骤S102：计算主蒸汽压力与预设压力的压力变化差值，所述预设压力为汽轮机稳定负荷状态下的汽阀的主蒸汽压力；Step S102: Calculate the pressure change difference between the main steam pressure and the preset pressure, the preset pressure being the main steam pressure of the steam valve under the steady load state of the steam turbine;
在本实施例中，在进行主汽阀全行程关闭试验时，机组的稳定负荷400MW，此时主蒸汽压力为19.51MPa，主蒸汽压力的超临界压力为23.18MPa；因此以19.51MPa为汽轮机稳定负荷的预设压力。In this embodiment, when the main steam valve is fully closed, the steady load of the unit is 400MW, the main steam pressure is 19.51MPa, and the supercritical pressure of the main steam pressure is 23.18MPa; therefore, 19.51MPa is used as the stable steam turbine Load preset pressure.
步骤S103：根据压力变化差值调节关闭试验中的实验动作，以使主蒸汽压力趋近预设压力。Step S103: Adjust the experimental action in the closing test according to the pressure change difference, so that the main steam pressure approaches the preset pressure.
作为本实施例的进一步优化，所述实验动作包括：汽阀的开关速率、实验间隔时长和锅炉燃烧量中的至少一种，即本发明可以根据实际阀门关闭实验工况，灵活选择不同的调节方式；例如可以采用其中的一种方式进行调节主蒸汽压力，也可以是两种方式的组合或者三种方式同时进行调节主蒸汽压力。As a further optimization of this embodiment, the experimental action includes: at least one of the switching rate of the steam valve, the duration of the experimental interval, and the combustion volume of the boiler, that is, the present invention can flexibly select different adjustments according to the actual valve closing experimental conditions. Ways; for example, one of the ways can be used to adjust the main steam pressure, and it can also be a combination of two ways or three ways to adjust the main steam pressure at the same time.
具体地，采用调节关闭实验中的汽阀的开关速率时，根据压力变化差值调节关闭试验过程中的实验动作，包括：Specifically, when adjusting the switching rate of the steam valve in the closing experiment, the experimental action during the closing test is adjusted according to the pressure change difference, including:
步骤a101：根据所述压力变化差值计算主蒸汽压力的变化幅度；Step a101: Calculate the variation range of the main steam pressure according to the pressure variation difference;
步骤a102：确定与主蒸汽压力的变化幅度匹配的汽阀开关速率的降低幅度；Step a102: Determine the reduction range of the steam valve switching rate matching the variation range of the main steam pressure;
在本实施例中，每一个汽阀开关速率的降低幅度对应有个变化幅度范围，判断计算出来的变化幅度落在哪个变化幅度范围中，然后选取对应的汽阀开关速率的降低幅度；例如可分为六个变化幅度范围，分别是5％-7.5％，7.5％-10％，10％-12.5％，12.5％-15％，15％-17.5％和17.5％-19％。In this embodiment, the reduction range of each steam valve switching rate corresponds to a range of variation, and it is judged which range of variation the calculated range of change falls in, and then the corresponding reduction range of the switching rate of the steam valve is selected; for example, Divided into six ranges of variation, namely 5%-7.5%, 7.5%-10%, 10%-12.5%, 12.5%-15%, 15%-17.5% and 17.5%-19%.
步骤a103：按照所述汽阀开关速率的降低幅度降低汽阀的开关速率。Step a103: Decreasing the switching rate of the steam valve according to the reduction rate of the switching rate of the steam valve.
在本实施例中，例如采集到的主蒸汽压力为22.46MPa，此时变化幅度为15.18％，则对应的汽阀开关速率的降低幅度为50％，当以2％/s的基准速率时进行开关实验时，则调整后的汽阀的开关速率为1％/s，每个变化幅度范围所对应的汽阀开关速率的降低幅度根据多次测试进行拟合得到。In this embodiment, for example, the collected main steam pressure is 22.46MPa, and the range of change at this time is 15.18%, then the corresponding reduction range of the steam valve switching rate is 50%, when the base rate is 2%/s. In the switching experiment, the switching rate of the adjusted steam valve is 1%/s, and the reduction range of the switching rate of the steam valve corresponding to each variation range is obtained by fitting according to multiple tests.
具体地，采用调节关闭实验中的锅炉燃烧量，根据压力变化差值调节关闭试验过程中的实验动作，包括：Specifically, the boiler combustion volume in the shutdown experiment is adjusted, and the experimental actions during the shutdown test are adjusted according to the pressure change difference, including:
步骤c101：根据所述压力变化差值计算主蒸汽压力的上升速率；Step c101: Calculate the rise rate of the main steam pressure according to the pressure change difference;
步骤c102：若所述主蒸汽压力的上升速率超过上升速率阈值，降低所述锅炉燃烧量。Step c102: If the rising rate of the main steam pressure exceeds the rising rate threshold, reduce the combustion volume of the boiler.
作为本实施例的进一步优化，若所述主蒸汽压力的上升速率未超过上升速率阈值，降低汽阀的开关速率，即采用步骤a01-步骤a03的调节步骤，以使主蒸汽压力趋近预设压力。As a further optimization of this embodiment, if the rising rate of the main steam pressure does not exceed the rising rate threshold, reduce the switching rate of the steam valve, that is, adopt the adjustment steps of step a01-step a03, so that the main steam pressure approaches the preset pressure.
具体地，采用调节关闭实验中的实验间隔时长时，根据压力变化差值调节关闭试验过程中的实验动作，包括：Specifically, when adjusting the experimental interval in the closing experiment, the experimental action during the closing test is adjusted according to the pressure change difference, including:
步骤b101：设定连续进行关闭实验的两个汽阀的实验间隔时长；Step b101: set the experimental interval length of the two steam valves for the continuous closing experiment;
步骤b102：前一个汽阀关闭实验结束且到达实验间隔时长后，判断压力变化差值是否降低至压力稳定区间；Step b102: after the previous steam valve closing experiment is over and the experiment interval is reached, it is judged whether the pressure change difference is reduced to the pressure stable range;
步骤b103：若压力变化差值降低至压力稳定区间，开始对后一个汽阀执行关闭实验；Step b103: If the pressure change difference drops to the pressure stable range, start to perform a closing experiment on the latter steam valve;
若压力变化差值未降低至压力稳定区间，增加实验间隔时长直至压力变化差值降低至压力稳定区间，开始对后一个汽阀执行关闭实验。If the pressure change difference does not drop to the pressure stable range, increase the test interval until the pressure change difference drops to the pressure stable range, and start the closing experiment for the latter steam valve.
在本实施例中，由于对一个调阀刚完成关闭实验后，机组的主汽压力还是会存在波动，即此时机组的流量指令与负荷需经过几个周期的振荡才能回归原始值，根据单个调阀的关闭实验的历史数据可知，在完成单个调阀的关闭实验后，需要10s左右机组的主汽压力才能趋于稳定。因此，在本实施例中，将10s作为设定连续进行关闭实验的两个汽阀的实验间隔时长，而不同实验工况下的实验间隔时长也不相同，因此可通过增加实验间隔时长，例如当压力变化差值未降低至压力稳定区间，则按1-2s的步长来增加初始设定的实验间隔时长；确保前一个调阀完成关闭实验后主汽压力才能趋于稳定再进行下一个调阀的关闭实验。In this embodiment, since the main steam pressure of the unit will still fluctuate after the closing experiment of a regulating valve, that is, the flow command and load of the unit need to go through several cycles of oscillation before returning to the original value, according to a single According to the historical data of the closing experiment of the regulating valve, after completing the closing experiment of a single regulating valve, it takes about 10s for the main steam pressure of the unit to become stable. Therefore, in this embodiment, 10s is used as the experimental interval length of the two steam valves that are set to continuously close the experiment, and the experimental interval lengths under different experimental conditions are also different, so the experimental interval length can be increased by, for example When the pressure change difference does not decrease to the stable pressure range, increase the initial experimental interval time by 1-2s steps; ensure that the main steam pressure can only stabilize after the previous valve adjustment completes the closing experiment before proceeding to the next one Valve closing experiment.
作为本实施例的进一步优化，本发明优选采用组合方式进行主蒸汽压力的调节，例如蒸汽压力上升速率超过或远超过上升速率阈值时，采用调节开关速率(步骤a01-步骤a03)、实验间隔时长(步骤b01-步骤b03)和锅炉燃烧量(步骤c01-步骤c02)的组合方式；当蒸汽压力上升速率低于上升速率阈值时，采用调节开关速率(步骤a01-步骤a03)和实验间隔时长(步骤b01-步骤b03)的组合方式。As a further optimization of this embodiment, the present invention preferably adopts a combination method to adjust the main steam pressure. For example, when the steam pressure rise rate exceeds or far exceeds the rise rate threshold, the switch rate (step a01-step a03) and the experimental interval are adjusted. (step b01-step b03) and the combination of boiler combustion (step c01-step c02); when the steam pressure rise rate is lower than the rise rate threshold, adjust the switch rate (step a01-step a03) and the experimental interval duration ( Combination of step b01-step b03).
在本实施例中，关闭实验过程中，经过对汽阀的开关速率、实验间隔时长和锅炉燃烧量的调整，高压调阀关小过程中压力上升较为平稳且幅度较小；整个试验过程中主蒸汽压力最低值为18.96MPa，最高值为19.96MPa，试验恢复后主蒸汽压力为19.08MPa与试验前(19.64MPa)相差0.56MPa左右，压力波动幅值控制在1MPa以内，能确保机组的安全运行。In this embodiment, during the closing experiment, after adjusting the switching rate of the steam valve, the experimental interval length and the boiler combustion volume, the pressure rise was relatively stable and the amplitude was small during the closing process of the high-pressure regulating valve; The lowest steam pressure is 18.96MPa, and the highest is 19.96MPa. After the test resumes, the main steam pressure is 19.08MPa, which is about 0.56MPa different from that before the test (19.64MPa). The pressure fluctuation amplitude is controlled within 1MPa, which can ensure the safe operation of the unit .
其次，本发明还对于同类型机组国产化改造后安全运行具有较强的借鉴意义。Secondly, the present invention also has strong reference significance for the safe operation of the same type of units after localization and transformation.
