Abstract: In conventional voltage supply networks, the balance between the power fed in by the generators and the power drawn by the loads is controlled by means of the frequency of the alternating voltage. In future intelligent voltage supply networks (smart grids) having many small decentralized plants, such control by means of the network frequency will become more and more difficult. Instead, a central electronic control signal is transmitted in a separate communication network to devices in order to control the decentralized generators and also loads. However, there is a risk of network instability if many decentralized plants are simultaneously switched upon reaching a preset threshold value. Therefore, according to the invention, preset threshold values are not directly used as threshold values, but rather suitable effective threshold values are derived therefrom. Thus, the threshold values assume different values for different devices in the smart grid, and an undesired simultaneous reaction of all control devices in the smart grid is prevented.

Abstract: An output circuit comprising a photocoupler (11) which transmits a control signal from a control circuit to the output side under the electrically insulated condition, a transistor (12) for driving the load, and a power source stabilizing circuit (15) which supplies electric power for driving the transistor (12) from a power source (13) of the load side. The power source stabilizing circuit (15) includes a low voltage detecting circuit and an input-output short-circuiting circuit. When the input voltage to the power source stabilizing circuit (15) is determined by the low voltage detecting circuit to be lower than a predetermined voltage, the input-output short-circuiting circuit is rendered conductive. As a result, the transistor (12) is driven even when the power source (13) of the load side has a low voltage, to meet a wide range of power source (13) of the load side.

Abstract: An uninterruptible power supply (UPS) system (100) comprises a plurality of UPS units (UPS-1, UPS-2) connected in parallel. The controllers (130) of the units are programmed to implement a voltage calibration procedure and a current calibration procedure, in order that measurements of voltage and current made by sensors within the different units will agree. In the current calibration procedure, the load is disconnected (302) while one of the units is selected as a master and operates in a voltage control mode (VCM) (Steps 304-308). Each other unit is selected in turn and operated in a current control mode (310, 312). Current measurements made in the master unit are communicated (314) via a data bus to the selected unit and compared (316) with measurements made in the unit itself. The unit adapts its current sensing gains to match the master unit.
