Flexible AC Transmission System (FACTS) is a power electronics-based system that can enhance controllability, capacity and flexibility of the AC power network. NR’s FACTS solutions are built upon in-depth acknowledge of existing transmission systems, providing utility companies with fast voltage regulation, effective active power control and load flow control to improve the reliability and quality of power supply.
SVC is a set of electrical devices for adjusting reactive power fast and effectively in high-voltage power grid, which can regulate voltage and power factor, keeping voltage stable and improving power quality. It is widely used in power transmission, HVDC converter station, industrial field and wind farm, and so on.
More InfoThe Static Synchronous Compensator is a voltage regulating device based on voltage source converters. It acts as a source or a sink of reactive power which is independent of AC system voltage. The STATCOM can adjust reactive power of power grid, improve power quality, and reduce grid losses and the impact on electrical equipment. It is extensively applied to power grid, renewable energy generation, steel mill, chemical plant, electrified railway, city subway, mine and so on.
More InfoThe fixed series compensation plays an important role in the intelligent network due to its effect on transmission lines, especially with long distances. It can increase the power capacity of the transmission network and optimize power flow dispatching, reduce power losses and make full use of power supply at the minimum generation cost.NR Electric’s PCS-9570 fixed series compensation offers complete FSC solutions. NR's PCS-9570 consists of capacitor, metal oxide arrester (MOV), damping circuit, spark gap, bypass switch, series compensator platform, electronic transduce…
More InfoHeavy ice coating can damage transmission lines and towers, ultimately leading to a power supply outage in partial or the entire grid network. To guarantee the safe operation of the power system in severe weather, NR Electric provides consumers with the PCS-9590 fixed DC de-icer and the PCS- 9591 relocatable DC de-icer for the protection of transmission lines. The DC output voltage is adjustable. Different DC short-circuit currents can be supplied according to the conductor’s diameter and length. In addition, the de-icer device can also be used as SVC to quickly compe…
More InfoNR Electric’s PCS-9578 Controllable Shunt Reactor (CSR) is a shunt-type reactive power compensation system for supplying step-changing reactive power with fast response time and low-cost maintenance. It is designed based on high leakage reactance transformer and high-power thyristor semiconductor technology.CSR is used to solve the contradiction between reactive power compensation and restraining over-voltage especially in an extra-high voltage and long distance power transmission system. It can adjust the reactive power to stabilize the line voltage and achieve a reasonable …
More InfoUnified Power Flow Controller (UPFC), as the representative of the third generation of FACTS devices, is by far the most comprehensive FACTS device. In the steady state of power system. It can implement power flow regulation, reasonable control of line active power and reactive power and improvement of the transmission capacity of power system. In the transient state of power system, it can realize fast-acting reactive power compensation, dynamical support of the voltage at the access point and improvement of system voltage stability. Moreover, it can improve the damping …
More InfoPCS-9571 fault current limiter (FCL) is based on fast switch, highspeed sampling and fault identification control system, combined with high-potential isolation power supply equipment to achieve the effective suppression of short-circuit current of the power grid.During normal operation, the fast switch bypasses the current limiting reactor, and the entire fault current limiter exhibits a very low impedance state, which does not affect the normal operation of the power system. When a short-circuit fault occurs in the power system, the fault is quickly identified by the control system, …
More InfoWith the increasing demand of new power load on power quality,power quality has been greatly concerned by power enterprises and users. When lightning strike, power grid fluctuation, and large-capacity impact load suddenly appear, voltage decline temporally will be inevitable.Voltage decline can cause sensitive equipment, such as PLC controller, frequency conversion & speed regulation, various digital equipment, being damaged;As a result, production lines or motors are shut down, and many enterprises equipped with precision processing lines suffered economic losses.PCS-9564A dyn…
More InfoShore power system enables vessels to shut down their auxiliary engines and use shoreside electricity power supply while at berth. Auxiliary diesel engines run by vessels consume lots of fuel and produce a large quantity of pollutants, including polluting emissions, noise and vibration. Shore power helps to reduce energy waste and costs and to improve the environment in port.The PCS-9569 shore power system of NR Electric enables the shore-to-ship power connection. It helps to adjust de the grid electricity to appropriate vessel frequency so as to enable the reliable and high-quality…
