风电场光伏电站接入电网技术规定.ppt
风电场、光伏电站接入电网必须严格遵循GB/T 19963-2011及对应光伏并网技术标准，核心围绕有功控制、无功电压、低电压穿越、电能质量、二次系统、并网检测六大刚性要求执行，不满足则无法并网。
有功功率层面，风电场需具备调频调峰与连续平滑调节能力，20% 额定出力以上必须响应调度指令，功率变化按装机容量设严格限值，仅风速异常可豁免；光伏电站功率变化速率不超 10% 装机容量 /min，辐照度降低可例外。两类电站均需在电网频率超 50.2Hz 时降功率或切机，事故状态下服从紧急切除指令。
功率预测为强制配置，风电场全覆盖、10MW 及以上光伏必装，需提供 0-72h 短期与 15min-4h 超短期预测，每 15 分钟滚动上报、每日报送次日曲线，且需达标预测精度。
PPT共66页，页数太多不在一一叙述......
无功与电压控制按电压等级分层配置，机组 / 逆变器功率因数需在超前 0.95 至滞后 0.95 可调，不足则加装补偿装置；并网点电压需稳定在标称电压 97%-107%（高电压等级 100%-110%），主变优先选用有载调压型。
低电压穿越为核心安全门槛，风电场电压跌至 20% 额定值需不脱网运行 625ms，光伏电站电压跌至 0 需维持 0.15s 不脱网，故障清除后风电场以≥10% 额定功率 / 秒、光伏以≥30% 额定功率 / 秒恢复出力，高电压等级光伏还需具备 30ms 内响应的动态无功支撑能力。
二次系统需满足双路由通信、故障录波、UPS 供电≥40min 等要求，220kV 及以上场站必配 PMU；并网检测强制实施，风电场累计新增 40MW、光伏累计新增 10MW 需重测，6 个月内提交合格报告方可持续并网。
