3 system requirements
3.1 Composition
The independent photovoltaic system mainly includes the following subsystems:
- Main control and monitoring subsystems: Monitor the overall operation of the photovoltaic power generation system and the interaction between the various subsystems, and it can also act on the load;
- Photovoltaic subsystem: a unit that converts direct solar radiation energy into direct current energy;
― Power Regulator: Transforms electrical energy into one or more systems suitable for subsequent load use;
―Energy storage subsystem: It is used to store electrical energy and meet the requirements of continuous power consumption. Including energy storage devices and input-output control devices.
In a particular photovoltaic power system design, certain parts of the above subsystems may be omitted, and some of the components of the subsystems may appear in a single or combined form. For example, the control equipment used in the PV system generally has both the main control and monitoring functions and the input-output control function in the energy storage subsystem; the inverter may have some functions of the power conditioner, but may also include some energy storage subsystems. Lose people an output control function.
As an independent photovoltaic system and general load interface power distribution system, generally not as part of an independent photovoltaic system, but in the photovoltaic system engineering construction often supporting distribution system engineering construction, so in this standard, the distribution system will not be detailed Requirements, its basic requirements, see Chapter 5 "Other requirements."
The main components of the system should use qualified products that have passed relevant quality inspection or certification.
3.2 System power supply protection rate
The system power supply guarantee rate, that is, the percentage of the time that the load can be supplied during the year. The first failure of the system is due to the lack of power generation due to continuous rainy days, the storage energy of the energy storage subsystem can not meet the power consumption of the system load, and the second is due to system failure. The former depends on the system design configuration, and the latter depends on the system reliability and maintenance response time.
The determination of the system power supply guarantee rate mainly depends on the power requirements. The power supply protection rate for conventional power systems is generally 80% to 90%. For special systems that require high power supply protection rates, multiple power supply types should be considered to be complementary.
3.3 Safety Requirements

3.5 Design Principles
The design of an independent photovoltaic system should be based on the premise of meeting the requirement of system load power supply guarantee rate, comprehensive evaluation of environmental conditions and system performance, appropriate system scalability, and design of each subsystem. Photovoltaic system design is a very complex process. This standard only gives some general principles and requirements. The detailed requirements are given by future PV system design specifications.
Photovoltaic system load estimation is a key link in system design and cost accounting. The power of the load device can be obtained through measurement or product technical data, or refer to the relevant data of the same type of equipment. The time when the load device works can be calculated. Based on the measured load, the possible changes in the load should also be analyzed and evaluated to make design adjustments. When there is a DC load, the system DC voltage is generally selected as the maximum load DC voltage or the maximum load DC voltage; the AC voltage is generally selected according to the requirements of the load device.
The designed power of the PV subsystem should be designed for the monthly surface radiation of the inclined surface, and the standard daily power generation quantity multiplied by the photovoltaic system efficiency to meet the system load daily electricity demand. The design of the annual photovoltaic system with a balanced load on the monthly inclined surface should be less than the annual average daily radiation of the inclined surface, which is generally equal to the minimum monthly average radiation amount of radiation on the inclined surface. Unbalanced load The design of an independent photovoltaic system is mainly based on obtaining the maximum solar radiation during the load use period. PV subsystem voltage design should fully consider the voltage-temperature relationship of the photovoltaic system: The design operating voltage shall ensure that the battery is effectively charged throughout the year, and the maximum voltage that the system may reach may not exceed the maximum system voltage that a single photovoltaic module can withstand.
Note: The standard power generation capacity of the PV subsystem is equal to the power of the square array multiplied by the standard equivalent power generation. For the calculation of standard equivalent power generation, see IEC 61724. Photovoltaic system efficiency mainly consists of the temperature loss, combined loss, and occlusion loss of the photovoltaic subsystem, the charge and discharge efficiency of the energy storage subsystem, the inverter efficiency of the power conditioner, the power regulation loss, and the loss of the Hanning power grid. The efficiency of crystalline silicon photovoltaic system can be selected as reference 0.51.
In stand-alone PV systems, energy-storage batteries that are suitable for deep discharge and have a long cycle life should be used. The capacity of an independent photovoltaic system battery shall be able to store the electrical energy required to meet the load's power consumption within a certain range of the amount of radiation on the inclined surface. The design of the battery capacity should take into consideration the design life of the battery, the load condition, the unevenness of radiation on the inclined plane, the power of the PV subsystem, and the system efficiency. When the battery usage temperature deviates from the standard temperature, the battery design capacity should be properly adjusted according to the operating temperature.
For the determined power supply security rate, when the design power of the PV subsystem is small, the battery configuration capacity of the system is increased. The relationship between the PV subsystem power variation and the battery capacity variation depends on the radiation status of the PV system construction site. According to the principle of optimum design of PV subsystem power and battery capacity that meets the requirements of system power supply guarantee rate and the lowest overall system construction cost, it is appropriate to design the monthly sloping surface daily radiation quantity based on the minimum monthly average sloping surface daily radiation quantity (or close to value). . When the PV subsystem design margin is not high, the battery capacity should not be selected too large; when the PV subsystem design margin is large, the battery capacity should not be selected too small.
Note: The design capacity of the crystalline silicon photovoltaic system battery should generally be not less than 2.44 times the daily generation capacity of the photovoltaic subsystem design standard.
The capacity of the power conditioner should take into account the power of the load, the power factor, the simultaneous rate of power usage, the load factor of the inverter and the unbalance coefficient of each phase.
The system design should have redundancy. The power regulator should have limitations and protection functions to meet the requirements of the system's reliable operation. For the system with high power supply guarantee rate, the key equipment backup or modular redundant configuration can be considered to improve the system's reliability. Sex.
System design should also consider explosion-proof, anti-static, anti-theft and other security design.
The system design should consider the geographical conditions of the establishment site, such as high altitude, coastal areas, islands and wet environments.
For systems with higher altitudes, design should take full account of the special geographical conditions of the site establishment, such as: low air pressure, low air density, poor heat dissipation conditions, etc., to ensure that the pressure range of the exhaust valve of sealed batteries and the electronic components Thermal characteristics. For systems with high or low ambient temperature, in addition to the relevant requirements for the temperature adaptability of key equipment design and selection, special consideration should also be given to temperature control design of the battery room.
Systems engineering in earthquake-prone areas should consider corresponding seismic design, including civil engineering, square array support, and battery racks.
The environmental meteorological data used in the design mainly include: site location (including location, latitude, longitude and altitude, etc.), meteorological data (including monthly total solar radiation, direct radiation or scattered radiation, annual average temperature, maximum and minimum temperatures, and Long continuous cloudy days, maximum wind speed, hail, snowfall, lightning, etc.). In the absence of complete meteorological data, reference may be made to meteorological data at similar conditions or using empirical formulae/methods for estimation.
Comprehensive optimization of system design should be carried out in order to improve system efficiency and better meet system power supply guarantee requirements. In the design of system parameters, the corresponding technical parameter values ​​recommended by this technical specification should be selected as far as possible, and can also be designed according to the user's special requirements. Since the system design involves environmental meteorological parameters such as solar radiation and other complex calculations, computer-aided design should be adopted.

a) Calculate the load power consumption and determine the power supply voltage level;
b) According to the load power and system power supply guarantee rate requirements, combined with solar radiation resources, site conditions, system efficiency factors, choose the azimuth, optimize the tilt angle, calculate the amount of photovoltaic modules, determine the selection of photovoltaic modules, square array electrical structure design;
