MCR-type high voltage static var compensation installations

The low-tension coil is wound and cured with insulating cloth which is pre-impregnated by copper foil and epoxy resin. The iron core is made of high permeability cold-rolled grain-oriented silicon steel sheets with smaller magnetostriction, the processing of which is supported by the longitudinal and transverse shear, as well as an iron core stacking and flipping table, so as to ensure excellent performance. The application of multi-step stacking process homogenizes magnetic flux and reduces noise and loss. The product functions excellently due to its strong short-circuit resistance, safety and reliability, environmental protection and energy conservation, and direct operation in the load center.

Product Introduction

  • 产品描述
  • The HV magnetically static var compensator (MSVC) is designed with a magnetically controlled reactor branch, a capacitor bank branch, and an intelligent control system. The MSVC intelligent controller collects the voltage and current signal of the system to calculate its reactive power compensation amount. By adjusting the output capacity of the magnetically controlled reactor, full capacity stepless regulation of inductive and capacitive reactive power can be achieved. As the device compensates fast and accurately with changes in load, the real-time power factor of the system is maintained above 0.95.

    The device's core component - MCR, comprehensively apply advanced manufacturing technologies such as magnetic circuit parallel leakage self-shielding patented technology, integrated with large-scale transformers, high-voltage transformers, high-voltage capacitors, and power electronic control. The core adopts design methods such as magnetic density non-saturation, symmetric splitting, and independent AC/DC magnetic circuits. The windings utilize design methods such as auto-coupling, series-parallel connection, and structural symmetry. Adopting the design of overall electromagnetic structure and control scheme, maintenance-free and unmanned operation are realized. Through above technological measures, the losses, noises, and harmonic content of the MCR are effectively reduced, resulting in a rational structure, reliable quality, low cost, advanced performance, mature manufacturing process, stable operation, maintenance-free operation, and unmanned operation in substations.

    Advantages:Automatic stepless fast compensation, magnetic circuit parallel leakage self-shielding, magnetic density non-saturation, low losses, low noises, low harmonic, maintenance-free, and unmanned operation

     

    1.MSVC Intelligent Controller
    MSVC Intelligent Controller is a three-phase MCR intelligent controller designed and developed for three-phase power systems. It supports various topologies, up to 4-channel capacitor auto-switching, automatic capacity adjustment of MCR, dual-master-variable mode, remote detection and setup, and 4 different control modes of integrated, reactive power, voltage, and power factor. The hardware adopts dual ARM and dual system design, integrating comprehensive measurement, operation, analysis, protection, control and compensation in one microcomputer controller. The HMI of the controller is designed separately from the main controller, which is easy for users to install and operate.
