Power Plant Controller
The Power Plant Controller is compatible with all our models of solar inverter, converter and STATCOM. Installed at the generating plant’s interconnection point, it provides an interface between the grid operator and the equipment that makes up the plant. It complies with even the most restrictive requirements of grid connection regulations.
The PPC can be configured to meet the most restrictive standards of electrical grids of all kinds. Operating subject to the instructions of an external controller, it offers a great variety of methods of control to help ensure the quality and stability of the electrical system.
Active Output Control
The PPC allows you to regulate active power in an open or closed loop. In an open loop, the active power measured at the interconnection point should be equal to its defined rating, minus plant power losses. In a closed loop, availability of the command reference depends on sufficient active power being available in the plant.
Active power can be adjusted automatically in response to high- or low-frequency events.
Reactive Output Control
The PPC allows you to regulate reactive power in an open or closed loop. In an open loop, the reactive power measured at the interconnection point should be equal to its defined rating, minus plant power losses. In a closed loop, availability of the command reference depends on sufficient reactive power being available in the plant.
Potential Factor Control
This control mode is implemented in a closed loop. It inputs are the active power measured at the interconnection point and the adjusted reference value of the power factor obtained at that point.
Depending on the voltage measured at the interconnection point and the defined voltage setpoint, the PPC controls the equipment that makes up the plant system based on the value of the inductive or capacitive reactive power supplied as required to reduce or increase the voltage reading at the interconnection point in order to reach the adjusted reference setpoint.
Control of Reactive-Voltage Potential
Reactive potential can be adjusted automatically in response to high- or low-frequency events.
Power Electronics will be attending Solar Power International (SPI), Energy Storage International, and North America Smart Energy Week at the Salt Palace Convention Center in Salt Lake City, Utah, from 23 to 26 of September. This is the largest gathering of industry experts, leaders, and professionals from the solar, energy storage, smart energy, microgrid solutions, and EV infrastructure industry in North America.
At the beginning of 2017, the irrigation sector had already been making photovoltaic installations for direct supply of private pumps, mostly isolated, to replace or complement the use of generator sets for several years. At that time, Power Electronics SD700SP drive was already the most installed. With the implementation of this solar pumping system it was possible to reduce operating costs and increase energy efficiency.
The head of the solar division of Power Electronics for Latin America, Raquel Igualá, has highlighted the importance of knowing exactly the grid code that will be required prior to the sizing of a photovoltaic plant, in its participation in the portal’s interview cycle of news specialized in renewable energies of Latin America “Energía Estrategica”.
