Tracker Assembly — Torque Tube and Drive Installation
Ren, we're assembling Tracker Row 17 today — this is a single- axis tracker, 90 modules per row, 280 feet long. The torque tube sections need careful alignment before we bolt them up.
任工，今天组装第17排跟踪支架——单轴跟踪器，每排90块组件，长280英尺。 扭矩管段组对之前需要仔细对中。
任工: Got it. Each torque tube section is 45 feet long — we have 6 sections for this row plus one at the drive end that's shorter. They're 6-inch diameter round tubes, galvanized, with flanged couplings at the joints.
好的。每段扭矩管45英尺长——这排6段，再加驱动端一段短的。直径6英寸 圆管、镀锌、接头处有法兰联轴器。
装配主管: Sections are on the installation stands. I'm aligning the coupling flanges now — using a laser to ensure straightness. Max allowable misalignment is 0.06 inches at the coupling. All flange bolts are tightened in a star pattern to 85 ft-lbs.
管段已放到安装支架上了。用激光正在对法兰——确保直线度。联轴器处最 大允许偏差0.06英寸。所有法兰螺栓按星形顺序打紧到85英尺-磅。
After the tube is assembled, install the module rails — the purlins that run perpendicular to the torque tube. They bolt onto the tube at pre-marked positions. Make sure they're centered — if they're off, the module clamps won't line up.
扭矩管装好以后，装组件檩条——与扭矩管垂直的横条。按预标位置穿螺栓 固定在扭矩管上。确保居中——偏了的话组件压块就对不上了。
任工: 驱动装置那边——减速机装上去了吗？
The drive end — is the slew drive mounted?
Yes, the slewing drive is bolted to the drive post. The output shaft engages the torque tube through a spline coupling. We're aligning the drive motor and gearbox now. After that, we mount the tracker controller — the TCU — on the drive post and wire it to the motor, the inclinometer, and the DC power supply from the combiner box.
是的，回转减速机已用螺栓固定在驱动立柱上。输出轴通过花键联轴器与扭 矩管啮合。现在正在对驱动电机和变速箱。之后把跟踪控制器TCU装在驱动立 柱上，接线到电机、倾角传感器和汇流箱来的直流电源。
任工: QC检查：扭矩管直线度偏差0.04英寸——在0.06英寸公差内。所有法兰螺栓 扭矩抽检10%——都在83-87英尺-磅范围内。机械装配验收合格——可以上组 件了。
QC check: torque tube straightness deviation 0.04 inches — within the 0.06-inch tolerance. Torque audit on 10% of flange bolts — all between 83-87 ft-lbs. Mechanical assembly accepted — ready for module mounting.
Tracker Commissioning — Calibration and Backtracking
Ren, Row 17 is mechanically assembled and modules are on. Now let's commission the tracker. First, calibrate the inclinometer — the tilt sensor must know where "true horizontal" is.
任工，第17排机械组装完毕、组件已安装。现在调试跟踪器。先校准倾角 传感器——传感器必须知道真正的"水平"在哪里。
任工: 倾角传感器已装在扭矩管上。把跟踪器手动放到水平位置——用数字水平仪验 证——然后通过TCU设置零位。
Inclinometer is mounted on the torque tube. We manually slew the tracker to horizontal — verify with a digital level — then set the zero position through the TCU.
Good. Now set the tracking parameters: maximum angle ±60 degrees, backtracking enabled. The latitude and longitude for the astronomical algorithm are already loaded. Run the full- range test — slew from -60° to +60° and back.
好。现在设定跟踪参数：最大角度±60度、开启逆跟踪。天文算法的经纬度 已经下载好了。跑全行程测试——从-60°转到+60°再回来。
SCADA技工: 我在SCADA上监控——速度稳定，每个限位信号都收到了。全行程时间大约 4分钟——正常。
I'm monitoring on SCADA — speed is steady, both limit signals received. Full-range travel time is about 4 minutes — normal.
任工: 现在验证逆跟踪。早上日出的时候，如果太阳位置很低，前面一排跟踪器会 遮到后面一排。逆跟踪算法会在太阳位置低时故意减小跟踪角——"反方向"转 ——以减少遮挡。平摊光线损失比互相遮挡好。
Now let's verify backtracking. In the early morning when the sun is low, the row in front would shade the row behind. The backtracking algorithm deliberately reduces the tracking angle — slews "backward" — to minimize shading. Spreading the light loss across the rows is better than letting them shade each other.
Simulating sunrise at 7:00 AM with a low sun angle... tracker is backtracking to -35° instead of the ideal -55°. Back- tracking angle matches the calculation. Row-to-row shading eliminated. The algorithm is working correctly.
模拟早上7:00日出、太阳角度低……跟踪器逆跟踪到-35°而不是理想值 -55°。逆跟踪角度与计算值吻合。行间遮挡已消除。算法运行正确。
SCADA技工: 大风保护也测试了——风速计读数超过35 mph时，所有跟踪器应自动平放。 我可以仿真大风信号……跟踪器在45秒内全部平放到0°，状态在SCADA上报 警。
High-wind stow is tested too — anemometer reading above 35 mph should auto-stow all trackers. I can simulate a high wind signal... trackers all stow to 0° flat within 45 seconds. Status alarms on SCADA.
任工: 第17排调试完毕。重复同样的过程调试其余15排。全部调好后做阵列级联动 测试——确保所有跟踪器同步运动。
Row 17 commissioning complete. Repeat same process for the remaining 15 rows. After all are done, run the array-level synchronization test — make sure all trackers move in sync.
