Problems solved by technology
The existing technology does not consider the load power of each controller first. When the load power of each controller is quite different, even if the opening time is arranged reasonably, the difference in load power will still cause a large impact on the grid environment. shock
Assuming that the load power of each controller is the same, if the turn-on time of each controller is greater than 50% of the power regulation cycle, according to this sorting method, it will still cause a great impact on the grid environment
like figure 1 As shown, the load powers of the four controllers are the same, and the opening time is the same, all of which are greater than 50% of the power adjustment period. After the opening time is allocated according to the existing technology, there will be a period of time in the middle of the power adjustment cycle. Opening, causing a big impact on the power grid

Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.
[0039] In the technical solution of the present invention, multiple thyristor power controllers work in the same power grid environment. Each controller can be set as the master controller or slave controller, and can also be used independently for a load power distribution box as the master controller. The master controller is connected with each slave controller through communication lines. The slave controller sends its own load power and turn-on time to the master controller, and the master controller sends the thyristor turn-on time node to each slave controller after calc...

The invention relates to a load power control method used for a thyristor power controller, and the thyristor power controller. The controller comprises a master controller and slave controllers. The method comprises the following steps that the slave controllers send respective thyristor power and switching-on time to the master controller; the master controller respectively sends the switching-on time node of each thyristor to each slave controller after the operation; and each slave controller switches on the respective thyristor according to the received time node. According to the invention, a plurality of thyristor power controllers can simultaneously work on a power grid, and impact on the power grid by current harmonics and voltage harmonics can be reduced.
Description
technical field [0001] The invention relates to a load power control method applied to a thyristor power controller and a thyristor power controller. Background technique [0002] The thyristor power controller can adjust the equipment to output alternating current with constant voltage, current and power according to user needs. When a thyristor power controller operates alone, it mainly controls the opening and closing of the thyristor to supply power to the equipment. According to the power required by the user, the thyristor will be turned on and off frequently. This process will cause frequent impacts on the environmental grid and generate certain harmonics on the grid. When multiple power controllers work on the same power grid, if each controller is in an independent working mode, the turn-on and turn-off times of the thyristors are assigned independently, which will cause strong and frequent damage to the power grid of the factory or its environment. The impact of ...
