When a fault occurs, pay attention to analyze the cause of the fault from the fault phenomenon, and analyze the structure combined with the principle, from the surface to the inside, easy first and then difficult. The following three problems should be considered first when the fault occurs: (1) what phenomenon appears before the fault occurs?

(2) 故障发生前进行过哪些保养、检修工作?

(2) What maintenance and repair work have been carried out before the fault occurs?

(3) 以前是否遇到类似的情况? 怎么处理的?另外,当机组允许在运行中判断问题所在时,可在运行中判断。

(3) Have similar situations been encountered before? How to deal with them? In addition, when the unit is allowed to judge the problem during operation, it can be judged during operation.

例如:机组运行时若发现排温过高或某一缸排温突然变化大,应首先在设备运转状态下检查各缸燃气调节阀有无松动现象,若排除燃气调节阀没有松动后问题依然存在,应停机检查其点火系统如:火花塞和点火线圈等是否存在问题;若出现排温异常,则要区分是单缸还是整体排温异常,如果是单缸异常,应考虑是不是仪表显示不正常,可采用测量热电动势或倒线的方式加以排除;如果是整体异常,应考虑气体浓度是否发生了变化或是否存在点火不良。

For example, if the exhaust temperature is too high or the exhaust temperature of a certain cylinder suddenly changes greatly during the operation of the unit, first check whether the gas regulating valve of each cylinder is loose under the operation state of the equipment. If the problem still exists after the gas control valve is ruled out to be not loose, the ignition system, such as spark plug and ignition coil, shall be shut down to check whether there is any problem; if the exhaust temperature is abnormal, It is necessary to distinguish whether the single cylinder or the overall exhaust temperature is abnormal. If the single cylinder is abnormal, whether the instrument display is abnormal should be considered, which can be eliminated by measuring thermoelectric EMF or reversing the line; if it is overall abnormal, whether the gas concentration has changed or whether there is poor ignition should be considered.

排除故障时,当没有有效手段查清故障原因时,可以采用置换法。例如当怀疑点火控制器出现故障时,检查和调整时需将点火控制器连接到PC 电脑或专用手提编程器上进行调整,但基本上维护单位都不会配置这些检测设备,这时就可以把其他备用设备上的点火控制器拆过来装上后开机运转,通过观察类似的故障现象是否再次发生来判断是不是点火控制器损坏。

When troubleshooting, when there is no effective means to find out the cause of the fault, replacement method can be used. For example, when it is suspected that the ignition controller is faulty, it is necessary to connect the ignition controller to a PC or a dedicated portable programmer for adjustment during inspection and adjustment, but basically the maintenance unit will not configure these detection equipment. In this case, the ignition controller on other standby equipment can be disassembled, installed and started to run, Whether the ignition controller is damaged can be judged by observing whether the similar fault phenomenon occurs again.

燃气发电机组是适应世界环保要求和市场新环境而开发的新型发电机组。天然气发电机组主要分为两种，一种是联合循环燃气轮机，一种是燃气内燃机。燃气轮机功率比较大，主要用在大、中型电站，燃气内燃机功率比较小，主要用在小型的分布式电站。它是取代燃油、燃煤机组的新型绿色环保动力。充分利用各种天然气或有害气体作为燃料，变废为宝、运行安全方便，成本效益高，排放污染低，并适宜热、电联产等优点，市场前景十分广阔。

Gas generator set is a new type of generator set developed to meet the requirements of world environmental protection and new market environment. Natural gas generator set is mainly divided into two types, one is combined cycle gas turbine, the other is gas-fired internal combustion engine. The power of gas turbine is relatively large, which is mainly used in large and medium-sized power stations, while the power of gas-fired internal combustion engine is relatively small, which is mainly used in small-scale distributed power stations. It is a new green power to replace oil and coal-fired units. Making full use of all kinds of natural gas or harmful gas as fuel can turn waste into treasure, operate safely and conveniently, have high cost-effectiveness, low emission pollution, and are suitable for cogeneration of heat and electricity.

我国的天然气资源十分丰富，相对于我国丰富的天然气储量,天然气在我国一次能源消费中所占比例显得太小,未来具有大幅提高的潜力。

China is rich in natural gas resources. Compared with China's abundant natural gas reserves, the proportion of natural gas in China's primary energy consumption is too small, which has the potential to be greatly improved in the future.

在我国，由于受到天然气供应的影响，天然气发电尚处于初始阶段。真正大面积的天然气发电作为分布能源站还要假以时日。现在的小规模天然气发电主要是在油田、气田以及机场、酒店、医院等。可以预计，随着天然气供应的愈加充足、供应范围的不断扩大，近几年天然气发电将会得到一个飞速的发展

In China, due to the influence of natural gas supply, natural gas power generation is still in the initial stage. It will take time for large-scale natural gas power generation to be a distributed energy station. At present, small-scale natural gas power generation is mainly in oil fields, gas fields, airports, hotels, hospitals, etc. It can be predicted that with the increasing supply of natural gas and the continuous expansion of the scope of supply, natural gas power generation will get a rapid development in recent years
