　　生物质气发电机组是民用建筑常用的应急电源。生物质气发电机组的正确选择是民用建筑电气设计中的一个重要问题。那么，在选择独立的生物质气发电机组时，如何根据负荷选择合适的容量呢？

　　Biomass gas generators are commonly used emergency power sources in civil buildings. The correct selection of biomass gas power generation units is an important issue in the electrical design of civil buildings. So, how to choose the appropriate capacity based on the load when selecting an independent biomass gas generator set?

　　1。设置原则一级高层建筑按一级负荷要求供电。二级高层建筑按二级负荷要求供电。《民用建筑电气设计规范》（闯骋闯/迟16-92）第3.1条：一个负荷由两个电源供电。当一个电源发生故障时，另一个电源不应同时损坏。在二次负荷条件允许的情况下，还应采用双向供电，特别是用于防火的二次负荷。电源应满足两个回路的要求。对于主负荷中特别重要的负荷，除上述两种电源外，还必须提供应急电源。

　　1. The principle is to provide power to first level high-rise buildings according to the requirements of first level load. Secondary high-rise buildings are powered according to the requirements of secondary loads. Article 3.1 of the "Code for Electrical Design of Civil Buildings" (JGJ/t16-92): One load is powered by two power sources. When one power supply fails, the other power supply should not be damaged at the same time. When secondary load conditions permit, bidirectional power supply should also be used, especially for secondary loads used for fire prevention. The power supply should meet the requirements of two circuits. For particularly important loads in the main load, in addition to the two power sources mentioned above, emergency power must also be provided.

　　根据本规定，环能制造厂总结了独立生物质气发电机组的选定原则：答：当民用建筑用电满足一级负荷要求时，如果城市电网能提供两个独立的电源（一主一备或互为备用），我们不需要配备生物质气发电机组。但当主负荷中有特别重要的负荷时，一般应设置生物质气发电机组作为应急电源。

　　According to this regulation, the Environmental Energy Manufacturing Plant has summarized the selection principles for independent biomass gas generators: Answer: When the electricity consumption of civil buildings meets the requirements of the first level load, if the urban power grid can provide two independent power sources (one main and one backup or mutual backup), we do not need to equip biomass gas generators. But when there are particularly important loads in the main load, biomass gas generators should generally be installed as emergency power sources.

　　叠.当电网只能提供一种供电方式时，为满足一、二次负荷供电要求，一般应设置生物质气发电机组。此时，生物质气发电机组将作为备用电源和应急电源。在大中型商业建筑中，为保证供电中断不会造成很大的经济损失，建议设置生物质气发电机组。由于城市电网不能完全独立，有时当一个电源发生故障或检修时，另一个电源可能同时发生故障。因此，为了保证民用建筑内消防设备和其他重要设备（如智能设备、通信设备等）的可靠供电.

　　B. When the power grid can only provide one power supply method, biomass gas generators should generally be installed to meet the requirements of primary and secondary load power supply. At this time, biomass gas generators will serve as backup and emergency power sources. In large and medium-sized commercial buildings, it is recommended to install biomass gas generators to ensure that power outages do not cause significant economic losses. Due to the fact that urban power grids cannot be completely independent, sometimes when one power source malfunctions or undergoes maintenance, another power source may also malfunction simultaneously. Therefore, in order to ensure reliable power supply for fire-fighting equipment and other important equipment (such as smart devices, communication devices, etc.) in civil buildings

　　2。选择生物质气发电机组容量。独立生物质气发电机组容量的选择没有统一的计算公式。有些只是由10%-20%的电力变压器容量决定的。有些是根据消防设备的总容量来计算的。如果容量选择过大，可能造成投资浪费，容量过小，一旦发生事故，可能达不到使用要求。那么，如何选择独立发电机组的容量呢？础.方案或初步设计阶段。独立发电机组容量按电力变压器总容量的10%-20%计算。叠.施工图阶段。建筑物用电负荷可分为叁类：

　　2. Select the capacity of biomass gas power generation units. There is no unified calculation formula for selecting the capacity of independent biomass gas generators. Some are only determined by 10% -20% of the capacity of power transformers. Some are calculated based on the total capacity of firefighting equipment. If the capacity is chosen too large, it may result in investment waste, while if the capacity is too small, it may not meet the usage requirements in case of an accident. So, how to choose the capacity of an independent generator set? A. Plan or preliminary design stage. The capacity of an independent generator set is calculated based on 10% -20% of the total capacity of the power transformer. B. Construction drawing stage. The electrical load of buildings can be divided into three categories:

　　首先是安全负荷。这是确保建筑物内人员和设备安全可靠运行的负担。如消防泵、消防电梯、防烟设备、应急照明设备、通信设备、重要计算机及相关设备等；

　　Firstly, there is the safety load. This is the burden of ensuring the safe and reliable operation of personnel and equipment inside the building. Such as fire pumps, fire elevators, smoke prevention equipment, emergency lighting equipment, communication equipment, important computers and related equipment, etc;

　　二是保证负荷，即保证建筑物运行的基本设备负荷，主要包括工作区照明、部分电梯及通道照明；

　　The second is to ensure the load, that is, to ensure the basic equipment load for the operation of the building, mainly including work area lighting, some elevators and passage lighting;

　　第叁类为一般负荷，即除上述负荷外的其他负荷，如空调、水泵等一般照明和动力设备。

　　The third type is general load, which refers to other loads besides the above-mentioned loads, such as general lighting and power equipment such as air conditioning and water pumps.

　　当建筑物必须配备生物质气发电机时，应考虑第一类负荷。

　　When buildings must be equipped with biomass gas generators, the first type of load should be considered.

　　第二种负荷是根据建筑物的功能和电网的状态来确定的。当建筑物功能要求较高或城市电网供电不稳定时，应考虑二次负荷。但是，如果仅添加第一个负载和第二个负载来选择生物质气发电机容量，则所选容量太大。因为在消防状态下，只能保证消防设备的运行，二次负荷不用。当电网在非灭火状态下被切断时，不使用灭火设备。我们可以选择两种容量中较大的一种作为生物质气发电机组的容量。

　　The second type of load is determined based on the functionality of the building and the state of the power grid. When the functional requirements of buildings are high or the power supply of urban power grids is unstable, secondary loads should be considered. However, if only the first and second loads are added to select the biomass gas generator capacity, the selected capacity will be too large. Because in firefighting mode, only the operation of firefighting equipment can be guaranteed, and secondary loads are not required. When the power grid is cut off in a non fire extinguishing state, do not use fire extinguishing equipment. We can choose the larger of the two capacities as the capacity for biomass gas generators.

　　我们应该根据不同的要求选择不同的生物质气发电机容量。如果您不知道如何选择，可以请工程师或设备技术人员为您计算或联系我们。
