产品概述

PRODUCT INTRODUCTION

九洲高压动态无功补偿装置是综合应用现代电力电子技术、电能控制技术、以及自动化技术而研制开发的新一代高科技产品，是一种能够为电力系统快速而连续地提供容性和感性无功功率的电力电子装置。采用晶闸管控制电抗器和固定电容器组，即TCR+FC的典型结构，能准确迅速地跟踪电网或负荷的动态波动，对变化的无功功率进行动态补偿，装置响应时间小于10ms，实现功率因数补偿至0.92以上。九洲SVC装置能进行连续、分相和近似线性的无功功率调节，同时，将固定电容器组FC做成多回路滤波器，能够滤除由相控晶闸管TCR引起的谐波。

JZE Static Var Compensator （SVC） is a new high-tech product developed based on modern power electronics, power control technique and automation technique. JZE SVC is one of the advanced power electronics equipment which provides fast and continuous capacitive and inductive reactive power supply to the power system. With the typical structure of thyristor controlled reactor (TCR) and fixed capacitor (FC), JZE SVC can follow the dynamic variation of the power system or loads rapidly to compensate the variable reactive power dynamically. The response time is less than 10ms. The power factor can be greater than 0.92. Continuous, single phase and almost linear regulation can be realized. Meanwhile, the fixed capacitor banks are used as filters to reduce harmonics injected into the power system by TCR operation.

本产品晶闸管阀体的电气和结构工艺设计先进，采用卧式，设备紧凑、运行可靠、维护工作量少。全数字化智能控制系统采用拆西门子6RA70系列全数字直流调速控制装置加触发传输和脉冲放大板驱动晶闸管阀串，采用西门子全数字控制系统Simadyn D进行软件设计，技术成熟，具有高度的运行可靠性和实用性。自主开发的功能模块能够满足各种复杂的控制和保护要求。为适应大功率电力电子设备在高压条件下的使用要求，采用智能型密闭式循环水冷系统，冷却效率高，运行可靠。PLC自动监控系统完成各种继电保护功能，并通过触摸屏的直观界面实现人机友好交流。

With the advanced electrical and structural design, thyristor valves are built up horizontally, which features a compact structure, reliable operation and few maintenance. The control unit uses 6RA70 Siemens Variable DC Drive and other functional boards to drive thyristor valves. The application software is designed based on Siemens Simadyn D Digital Control System. The SVC controller features high reliability and applicability. Functional modules developed by JZE can meet various complex demands of controls and protections. In order to adapt for high voltage applications, the intellectual closed and circulated water cooling system is used for the power devices, which features high cooling efficiency and high operation reliability. PLC automatic monitoring system is used to perform different relay protections, and the touching screen is used to realize straight-forward human-machine communication.
