7 Grid dispatch 7.1 Power Regulation Instructions According to the standard requirements, Ai-Logger can reliably regulate the power of the connected inverters in real time to ensure that the PV power plant can respond to the requirements of the grid company in time. There are two types of grid dispatch regulation: active power schedule and reactive power schedule.
Active power schedule Note ● When the power plant has limited power demand, the grid dispatcher needs to temporarily limit the active power input of the power plant, or directly disconnect all active power input of the power plant, that is, active power derating. ●...
7.2.2 Dry contact remote control Notice ● When setting this function, please make sure that Ai-Logger is correctly connected to Ripple Control Receiver. For details, please refer to 4.5 Connect to Ripple Control Receiver. Note ● Support configuration of up to 16 percentage values. ●...
Parameter name Setup Instructions Active power schedule Set to "Fix active power percentage limited ( open loop ) " to control the maximum power output of the inverter in mode different time periods. Start time If time periods need to be divided throughout the day or part of the day, limit the inverter to run at a certain set maximum power, and add records as needed.
7.3 Reactive power regulation Note Power grid companies require large power plants to have a certain ability to adjust ⚫ the voltage at the grid connection point. The grid dispatcher requires the power plant to absorb or inject reactive power into the grid connection point according to the real-time reactive power transmission in the power grid, that is, reactive power compensation.
Note ● Supports up to 16 power factor configurations. ● Tick √ in the box to indicate low level, Ai-Logger 's 4 -way DI is low level when connected to GND2, and high level when not connected. ● The state combination of DI1(GND2) DI4(GND2) must not be repeated, otherwise the command parsing will be executed abnormally.
7.3.4 Power factor fixed value control Parameter name Setup Instructions Reactive power schedule If the power grid company requires the power plant to output a constant power factor at the grid-connected mode point, and the inverter regulates the reactive power in real time according to the set power factor, set it to "power factor fixed value control".
8 Device Maintenance To ensure the Ai-Logger can run well for a long time, it is recommended to perform routine maintenance and troubleshooting according to the descriptions in this manual. 8.1 Routine Maintenance ● Make sure that no strong electromagnetic interference devices are placed around the Ai-Logger.
