项目挑战
光伏系统通过逆变器产生大量谐波电流。在该迪拜电站中，多台逆变器的叠加效应导致：
- 发电高峰时段功率因数低至 0.85
- 公共连接点 THD 水平超过 8%
- 电压波动影响敏感电网设备
- 可能面临电力公司的罚款
解决方案
CHITEK 部署了全面的电能质量解决方案，包括：
- 4 台 CHITEK SVG-300 静止无功发生器用于无功补偿
- 2 台 CHITEK AHF-200 有源电力滤波器用于谐波治理
- 集成监测系统用于实时电能质量追踪
项目成果
安装后数周内，该设施实现了：
- 功率因数从 0.85 提升至 0.99
- THD 从 8% 降至 3% 以下
- 消除电力公司罚款
- 年节省电费约 180,000 美元

The Challenge
Solar photovoltaic systems generate significant harmonic currents through their inverters. At the Dubai installation, the combined effect of multiple inverters created:
- Power factor as low as 0.85 during peak generation
- THD levels exceeding 8% at the point of common coupling
- Voltage fluctuations affecting sensitive grid equipment
- Potential penalties from the utility company
The Solution
CHITEK deployed a comprehensive power quality solution consisting of:
- 4 × CHITEK SVG-300 Static Var Generators for reactive power compensation
- 2 × CHITEK AHF-200 Active Harmonic Filters for harmonic mitigation
- Integrated monitoring system for real-time power quality tracking
Results
Within weeks of installation, the facility achieved:
- Power factor improved from 0.85 to 0.99
- THD reduced from 8% to below 3%
- Elimination of utility penalty charges
- Annual energy savings of approximately $180,000
