Grid-connection of gas generating units is a complex and critical process that requires attention to the following to ensure safe and stable integration into the grid:
Matching of technical conditions: First, the parameters of the gas generator set such as voltage, frequency, phase and phase sequence must be consistent with the power grid system. This is the basic premise of grid-connection, any parameter deviation may lead to grid-connection failure or grid fluctuation.
Equipment inspection and maintenance: Before the grid connection, the gas generator set should be comprehensively inspected to ensure that it is in good operating condition. At the same time, check the equipment and devices required for grid-connection, such as grid-connection switches, protection devices, etc., to ensure that they are intact and have normal functions.
Automatic synchronous device: Automatic synchronous device is the key equipment to ensure that the generator set and the grid phase and frequency synchronization. Before grid-connection, check whether the automatic synchronization device is in good condition and set the correct parameters to ensure the smooth progress of the grid-connection process.
Grid-connected operation specifications: grid-connected operation should follow strict specifications and processes, including confirming grid-connected conditions, adjusting unit parameters, issuing grid-connected instructions, etc. Operators should be familiar with the grid connection process, and have the appropriate operational skills and experience.
Safety protection measures: In the process of grid connection, safety protection measures should be taken, such as setting up isolated areas, equipped with fire equipment. At the same time, you should pay close attention to the operating status of the unit and the power grid, and take immediate measures to deal with any abnormal situation.
