CSP Common Library 是一個模組化的 Python 工具集,專為能源管理系統工業設備通訊設計。

特點

  • 8 層分層架構:Core → Modbus/CAN → Equipment → Controller → Manager → Integration → Storage → Additional
  • Async-first:所有設備 I/O 與管理器皆採用 asyncio
  • 多協議支援:Modbus TCP/RTU 與 CAN Bus 雙協議設備抽象
  • 策略引擎:PQ/QV/FP/Droop/Island/PVSmooth/LoadShedding/RampStop 等 10+ 內建策略
  • 功率補償:前饋 + 積分閉環補償(PowerCompensator),含 FF Table 自動學習
  • 動態保護:DynamicSOCProtection / GridLimitProtection 從 RuntimeParameters 即時讀取參數
  • 功率分配:Equal / Proportional / SOCBalancing 多機分配,含硬體限制 + 溢出轉移
  • Modbus TCP Gateway:宣告式暫存器映射、寫入驗證、資料同步,對接 EMS/SCADA
  • 韌性機制:CircuitBreaker(指數退避 + jitter)+ RetryPolicy
  • Event-driven:設備事件系統 + WeakRef 自動清理
  • 精度控制ExecutionConfig.interval_seconds 支援 float(sub-second 策略如 DReg 0.3 s);StrategyExecutor work-first + 絕對時間錨定漂移補償(v0.8.0)
  • NO_CHANGE sentinelCommand.p_target / q_target 支援 NO_CHANGE,策略可宣告「此軸不變更」,CommandRouter 跳過對應軸寫入,多策略 cascade 正確組合(v0.8.0)
  • Event-driven TriggerSystemController.attach_read_trigger(device_id) 綁定設備讀完即觸發策略,搭配 TRIGGERED/HYBRID 模式消除 phase drift(v0.8.0)
  • ContextMapping param_key:直接從 RuntimeParameters 注入 context 欄位,不需手動搬入 extra(v0.8.0)
  • Fluent BuilderSystemControllerConfig.builder() 鏈式配置
  • Operator PatternReconciler Protocol + TypeRegistry + YAML Site Manifest,K8s 風宣告式站點配置與自我修復調和迴圈(v0.9.0)
  • 按需安裝:Optional dependencies 避免引入不必要的套件

Quick Start

import asyncio
from csp_lib.modbus import PymodbusTcpClient, ModbusTcpConfig, Float32, UInt16
from csp_lib.equipment.core import ReadPoint, WritePoint
from csp_lib.equipment.device import AsyncModbusDevice, DeviceConfig

device = AsyncModbusDevice(
    config=DeviceConfig(device_id="inverter_001", unit_id=1),
    client=PymodbusTcpClient(ModbusTcpConfig(host="192.168.1.100")),
    always_points=[
        ReadPoint(name="voltage", address=0, data_type=Float32()),
        ReadPoint(name="power", address=2, data_type=UInt16()),
    ],
)

async def main():
    async with device:
        values = await device.read_all()
        print(f"Voltage: {values['voltage']}V, Power: {values['power']}W")

asyncio.run(main())

控制流程

設備讀取 → ContextBuilder → StrategyContext
                                ↓
                    StrategyExecutor(策略由 ModeManager 決定)
                                ↓
                    Command → ProtectionGuard → CommandProcessor
                                ↓
                    PowerDistributor → CommandRouter → 設備寫入
