KLD-UPQC Series Comprehensive Power Quality Control Equipment

As a kind of power quality control equipment with comprehensive compensation capability, it directly controls the power quality of the whole low-voltage electrical system, and can simultaneously meet the requirements of voltage and current quality problems for users.

PRODUCT OVERVIEW

Electricity is one of the prerequisites for social development. With the development of social economy, the increasing amount of electric load, the continuous advancement of electric power industry and the growing installed capacity of power grid, the contradiction between the supply and demand of power is gradually no longer the main contradiction of the power system. Power quality problems include many aspects, such as voltage quality, current quality, power supply quality and power consumption quality. Due to the nonlinear characteristics of the power system, system faults and nonlinear loads and other issues, power distribution network has various power quality issues; at the same time, the automation and intelligence of the production process and life as well as a variety of complex precise equipment raise higher demands for the power quality, thus the unified power quality control has become the pressing issue that needs to be addressed.

As an power technology equipment, KLD-UPQC series comprehensive power quality control equipment is characterized by superior performance and comprehensive function, which can be used to solve a variety of power quality problems of the distribution network. As a power quality control equipment with comprehensive compensation capability, it directly controls the power quality of the whole low-voltage electrical system, and can simultaneously meet the requirements of voltage and current quality problems for users.

CONNECTION MODE

KLD-UPQC is connected between the grid and the load, and the maintenance bypass switch is optional. The maintenance bypass switch turns off when a system fault occurs so that the system can be repaired.

POWER QUALITY

Power quality refers to the physical characteristics of a power supply equipment that does not interrupts and interferes with the electricity consumption by users under normal operating conditions.

PRODUCT CHARACTERISTICS

● Redundant design does not affect the reliability and continuity of the power supply, ensuring the load can be operated normally and continuously
● Adopts three-level inverter to improve the efficiency of the whole equipment, reduce losses and save power
● Control voltage dips and rises
● Control voltage harmonic distortion and current harmonic distortion of power supply system
● Reduce line loss, increase output power of the transformer, improve power factor of the system, and stabilize the voltage of power supply
● Improve grid efficiency and power quality of the power supply system
● Grid power factor is close to 1 after controlling within the range of equipment capacity, and the total harmonic filtering rate is more than 97%
● DSP intelligent monitoring, high-speed detection and operation ensure accurate and effective detection and compensation control
● Standard modular design, module or component (plug-in unit) structure for power circuit and control circuit. The same module can be interchanged to enhance the reliability and repairability in use
● Small and lightweight design has low requirements for space
● Daily maintenance-free
