Voltage Regulation. The Power Plant shall operate in accordance with the reactive capacity curve (or voltage curve) issued by the Dispatching Agency so as to ensure that the operation of the bus of the Power Plant is in the prescribed scope. If the Power Plant has lost its control of voltage, it shall immediately report it to the dispatcher on duty of the Dispatching Agency.
Voltage Regulation. The Owner shall provide the necessary voltage regulation equipment to prevent the Facility from causing excessive voltage variations on the LES electrical system. The voltage variation caused by the Facility must be within the ranges capable of being handled by the voltage regulation facilities used by LES.
Voltage Regulation. This interconnection study has concluded that generator voltage regulation controls will be required. The transformer voltage drop must be automatically accounted for within the regulator controls. Initially the voltage on the 120 kV side of the step up transformer should be held to 122 kV. After the plant has become operational, Far West and SPPCo. will have to evaluate whether this is a workable voltage.
Voltage Regulation. (1) The voltage of the 110kv busbar of the Power Plant shall be the examination point for the voltage of the power grid, which shall be operated within the upper and lower limits of the voltage curve in the monthly plan released by Sanming Local Dispatching Agency to ensure the monthly qualification rate of the voltage of the examination point being 100%.
Voltage Regulation. The Power Station shall be operated in accordance with the reactive output curve (or voltage curve) released by the Power Dispatching Agency to ensure the operation of the busbar voltage of the Power Station within the prescribed range. In the event that the Power Station has lost its control on the voltage, such conditions shall be immediately reported to the on-duty dispatcher of the Power Dispatching Agency.
Voltage Regulation. (1) In case the power grid requires reactive optimization, the Power Plant shall adjust according to the reactive load released by the dispatching agency of Pingnan county, and make adjustments whenever necessary.
Voltage Regulation. (1) The voltage test point of the Fujian power grid is 110KV busbar. Ningde Local Dispatching shall provide the maximum and minimum voltage curves of the voltage test point to the Power Plant. The Power Plant shall monitor and adjust the voltage at the test point under the operation of the generator set according to the “Dispatching Codes” to ensure the monthly pass-rate of the voltage at the test point reaching 100%.
Voltage Regulation. Seller shall provide voltage regulation for the Facility at the Point of Interconnection. The voltage regulation shall be able to maintain voltage by utilizing the entire range of the Facility’s Mvar capability. For this purpose, Mvar high and low limits based on the capability curve shall be provided to the Company EMS via telemetry. The Company System Operator shall be able to specify the voltage target remotely from the EMS.
Voltage Regulation. At the load end, the power required by the load, S, can be given by the formula below: 𝐴𝑝𝑝𝑎𝑟𝑒𝑛𝑡 𝑃𝑜𝑤𝑒𝑟 𝑆 = 𝑉𝐼 For a constant power load, as the voltage at the load bus is reduced the current required by the load increases, which increases the current flow in the distribution lines and increases the power losses. Therefore another strategy for reducing the losses in to control the voltage. The voltage control technology can be implemented at the system level by optimising position of tap changing transformers. The distribution networks are equipped with Automatic voltage control schemes (AVC) which measures the local voltage and compares this with a target voltage. The tap ratio of the transformer is then adjusted to achieve the target voltage. An AVC may have line drop compensation, using line current and impedance to calculate the voltage drop at the end of the line. The AVC+LDC will then control the tap ratio of the transformer to achieve the target voltage at the end of the line. Figure 3-2: Regulating voltage profile
Voltage Regulation. The DR [distributed resource] shall not actively regulate the voltage at the PCC [unless required by NEPOOL’s operating procedures]. The DR shall not cause the Area EPS service voltage at other Local EPSs to go outside the requirements of ANSI C84. 1 -1995, Range A.
