  • 引言

    随着新能源并网规模持续扩大,电力系统中电力电子设备占比显著提高,系统动态特性呈现出多时间尺度并存的特点。相较以同步机为主的传统电力系统,新能源并网系统同时包含快速控制、电磁暂态以及较慢的系统响应过程,对仿真模型的准确性和适用性提出了更高要求。

    在实际工程中,不同研究目标对应不同仿真侧重点[1]。电磁暂态仿真基于瞬时值建模,适用于电力电子控制及快速暂态问题分析,常用工具包括PSCAD/EMTDC、DIgSILENT、MATLAB/Simulink等;机电暂态仿真基于基频相量建模,更适合系统层面的动态特性分析,典型软件有PSASP、PSS/E;此外,数模混合仿真(硬件在环)广泛应用于控制与保护系统的实时验证,常见平台包括ADPSS、RTDS、RT-LAB。

    由于不同仿真方法在建模精度、计算效率和适用场景方面各有侧重,单一仿真工具往往难以满足工程分析的全部需求。如何在不同仿真工具间复用同一套控制与保护模型,保证模型行为一致并降低维护成本,成为电力系统仿真中的关键问题[2]。

    关于 IEEE/CIGRE 标准

    跨仿真平台应用中,模型复用的核心挑战在于算法一致性、接口统一性以及知识产权保护。相比直接移植源代码,基于动态链接库( DLL) 的模型封装方式在工程中更具可行性。

    EEE/CIGRE 建模标准正是在这一背景下提出[3]。该标准通过定义统一的 DLL 接口,使控制与保护算法能够被封装为标准化模块,并在不同仿真工具和平台中调用。仿真工具仅通过标准接口与 DLL 交互,而无需关心其内部实现,从而显著提升了模型的可移植性与复用性。下图给出了 IEEE/CIGRE DLL 在仿真工具中的典型调用方式[4]。。

    c65f8728-1d33-11f1-90a1-92fbcf53809c.png

    图1:IEEE/CIGRE DLL 接口示意图

    在工程实践中,常见做法是将现场控制与保护装置的“真实代码”封装为符合 CIGRE 规范的 DLL,使仿真模型在算法逻辑、参数设置和保护策略等方面与现场设备保持一致。

    需要指出的是,IEEE/CIGRE 标准的工程价值不仅体现在接口统一,还体现在对复杂仿真需求的支持能力。例如,模型需支持状态快照的保存与恢复,以适应不同仿真运行方式;同时还需支持多实例并行运行,要求模型在参数与状态管理上保持严格隔离,避免使用全局变量。这些能力在新能源场站和电力电子装置等应用场景中尤为关键。

    基于 Simulink 的 DLL 导出方案

    针对上述需求,MathWorks咨询服务团队开发了 Simulink 到 IEEE/CIGRE DLL 的导出工具。该工具支持按照 CIGRE 标准,将 Simulink 算法模型自动生成标准化 DLL。使得同一套算法模型可以在不同仿真环境中复用。

    c6b8a402-1d33-11f1-90a1-92fbcf53809c.png

    图2:Simulink导出CIGRE工具箱

    算法模型搭建

    控制与保护逻辑首先在 Simulink 中完成建模。模型应尽量模块化,便于后续在不同仿真场景中复用,并避免与具体仿真平台强耦合

    图3:Simulink算法模型示意图

    参数定义

    为支持 DLL 的多实例并行运行,必须避免在生成的 C 代码中使用全局变量。所有可调参数应定义为 Simulink.Parameter 对象,并存储在顶层模型的模型工作区中,存储类别设置为“模型默认”。下图展示了参数在模型工作区的定义方式。

    c76d8a5c-1d33-11f1-90a1-92fbcf53809c.png

    图4:参数定义示意图

    在工程应用中,参数通常采用结构体形式进行定义。结构体中各成员可在 CIGRE DLL 中作为独立参数访问。在模型引用层级中,应通过模型参数方式将参数逐级传递至下层模型。相关参数传递方式如下图所示:

    c7c7448e-1d33-11f1-90a1-92fbcf53809c.png

    图5:参数传递示意图

    顶层模型封装

    为生成符合 CIGRE 接口规范的代码,需要构建一个专用的顶层模型,用于包裹实际的算法模型。该顶层模型负责定义 DLL 的输入输出接口,并统一管理模型实例。下图用于DLL导出的顶层模型封装示例。

    c822c390-1d33-11f1-90a1-92fbcf53809c.png

    图6:顶层模型示意图

    在模型配置中,需要启用可重入函数和结构化 I/O,并将“每个顶层模型允许的实例数”设置为 Multiple,以确保模型能够支持多实例并行运行。相关配置选项如下图所示。

    c87993b4-1d33-11f1-90a1-92fbcf53809c.png

    c8cf8ac6-1d33-11f1-90a1-92fbcf53809c.png

    图7:模型配置示意图

    DLL 生成

    在完成模型封装与配置后,即可进入 DLL 生成阶段。在顶层模型中,将系统目标文件设置为 cigre.tlc,并选择相应的 CIGRE DLL 工具链,即可生成符合 IEEE/CIGRE 标准的 DLL。生成结果通常包括 DLL 文件及对应的接口头文件。

    c923840a-1d33-11f1-90a1-92fbcf53809c.png

    图8:DLL生成配置示意图

    验证与应用

    生成的 DLL 可导入 PSCAD 等电力系统仿真软件中进行功能与动态特性验证。在PSCAD侧,通常需要通过Fortran Wrapper 调用 DLL,实现模型与仿真系统的接口集成。通过对比仿真结果,可验证DLL模型在不同平台下的功能一致性。

    图9:DLL验证示意图

    结论

    MATLAB/Simulink 在算法开发与控制设计方面具有广泛应用基础。通过将 Simulink 模型导出为符合 IEEE/CIGRE 标准的 DLL,可有效实现模型在多种电力系统仿真平台之间的复用,显著降低跨工具建模和维护成本。该方法为新能源并网、电力电子控制以及多时间尺度仿真提供了一种工程化、可扩展的解决方案,有助于提升电力系统分析效率和模型一致性。

  • Ex-NFL star Shawne Merriman talks streaming, cautions league

    Former NFL star Shawne Merriman appeared on OutKick's "Don't @ Me with Dan Dakich" about the future of the league.

    NEWYou can now listen to Fox News articles!

    The picture the NFL wants you to have of America's most popular sport is that this is a steamroller crushing it at every turn, with revenues, ratings, salaries, and, of course, entertainment and drama breaking through one ceiling after another in a seemingly endless streak of success.

    And much of that is indeed an accurate portrait.

    But there's another snapshot the average fan is increasingly seeing and that's of an NFL that is taking more out of your wallet than ever, whether you're headed to games or watching at home.

    It's the NFL that was born in America but is looking to export games to feed fans abroad – obviously at the expense of packed stadiums at home.

    And, it is the NFL that has partnered with gambling conglomerates as a way of increasing revenue and interest, perhaps at the expense of feeding addiction.

    So, yes, the NFL is America's reality show. It's fun and captivating, but it's also unquestionably troubling at times. 

    So how did the NFL behemoth get here?

    "When I started in the NFL, it was the most popular sport," said former San Diego Chargers team doctor David Chao, who worked 17 seasons for the team. "By the time I was done, it was more popular than all the other sports combined.

    "And what's the fundamental difference? You go to a sports bar during baseball season. It's all men watching games. You go to a sports bar on Sunday during football season, it's half women watching games. They've doubled their audience. And they added fantasy. But what is fantasy? It's personal ownership and stake. It's personal stake in the games."

    Chao points out that fans years ago asked him whether a player was available for a game because they wanted the Chargers to win. Fans still care about their teams, but the league has added new fans that want to know that information because they want to set their fantasy team to win.

    Or they want to have their gambling bets win.

    The NFL's ‘Existential Threat’ 

    Gambling has become a revenue source for the NFL that simply didn't exist a decade or so ago. 

    The NFL has shifted from outright opposition to active commercial partnership with the sports betting industry. Caesars Entertainment now serves as the league's official casino sponsor while DraftKings and FanDuel are official sports betting partners.

    These agreements allow the partners to use NFL trademarks, promote betting activities in league media and engage fans with NFL-branded betting experiences. And while the NFL maintains boundaries designed to protect the integrity of the game, that is a too-thin line for anyone who understands how potential betting information works.

    "It's a disaster, it's the existential threat to football," said famed NFL agent Leigh Steinberg, whose career was Hollywood's template for Tom Cruise's character in the 1996 movie "Jerry Maguire." "All it takes is one inside piece of information being leaked to a gambler that's trying to do a prop bet or an athlete that actually shaves performance, and it's a slippery slope to having a true contest, and it starts to resemble wrestling.

    "Gambling is maybe good news for revenue, but it's bad news for the integrity of the game and continued fan interest."

    NFL Feeding Gambling Addictions

    Steinberg is the author of four books, including his latest, due out March 24, titled "The Comeback: A Playbook for Turning Life's Setbacks Into Victories." Part of that book details Steinberg's battle with alcohol addiction, and he's concerned that the NFL's ties to gambling could have a terrible effect on some of its fans.

    Beyond likely losing a lot of money, that is.

    "They're going to create a whole new generation of gambling addicts," he said. "Because certain people can't handle this. Second of all, if you don't feel the games are played on a level playing field with equal officiating, rules, every player trying his hardest … If you introduce into the fan's brain that there's a possibility that something else is going on other than what they see on the field, it's a disaster."

    There is already a faction of NFL fans on social media who refer to the NFL as scripted. Some NFL staff even publicly joke about this narrative. But all it takes is one player, innocently or not, sharing injury information that gets leaked into gambling circles as to affect betting lines, and the NFL would have a scandal on its hands.

    NFL Exporting Games Around Globe

    But none of this is so far slowing the NFL from its steady, seemingly inexorable expansion into becoming a global game.

    "In today’s world, we have to be global," Commissioner Roger Goodell told fans in Ireland last season before the Pittsburgh Steelers and Minnesota Vikings played in Dublin. "Every time we play an international game, fans say they want more. I really, truly believe our game can and will be global. Our job is to share our game with the rest of the world."

    The NFL will play a record nine international games in 2026 across four continents, seven countries and eight stadiums: 

    • London, U.K. (Two games in Tottenham Hotspur Stadium, One in Wembley Stadium)
    • Madrid, Spain (Bernabéu Stadium)
    • Melbourne, Australia (Melbourne Cricket Ground)
    • Mexico City, Mexico(Estadio Banorte)
    • Munich, Germany (FC Bayern Munich Stadium)
    • Paris, France (Stade de France Stadium)
    • Rio de Janeiro, Brazil (Maracanã Stadium)

    Paris, Melbourne and Rio are new additions to the International slate. And they won't be the last, if things go according to plan.

    "We would like to get to 16 games, so everyone is playing one game a year internationally," Goodell said.

    Players Do Not Want 18th Game

    But every game that is exported is a game that leaves the United States. 

    Well, the NFL has a long-range plan for that which may appease some fans but will surely displease players and that is adding another game. Even though Goodell cautioned during Super Bowl week that adding an 18th game was "not a given," he added that NFL owners want to discuss such an expansion with the NFL Players Association. 

    That's because the NFL definitely wants to some day offer an 18-game regular season and two bye weeks that begins on or before Labor Day and ends on the Sunday prior to President's Day. That plan would include two preseason games to give each team a dry run for a home and away game.

    "Our members have no appetite for an 18th regular-season game," NFL Players Association interim Executive Director David White said during the union’s annual Super Bowl week news conference in San Francisco.

    But the players' union has balked at additional games in the past. And then it has given in to additional games in collective bargaining in return for more money. So the league believes one more game can again be negotiated.

    NFL faces challenges with growth opportunities

    近期金价自2月高点5600美元附近一路回落,已跌破4500美元关键支撑,并一度测试4000-4100美元的200日均线区域,创下年内较大回调幅度。目前金价在4000-4100美元附近获得初步买盘支撑,出现带长下影线的阳线反转信号,但上方4450-4500美元阻力明显,短期仍显承压。整体来看,市场处于高位震荡修复阶段,避险情绪与获利了结交织,成交活跃但方向不明。

    基本面分析

    本次金价回调主要受两大短期压力驱动:

    海湾地区流动性紧张与实物抛压:伊朗封锁导致海湾国家石油收入大幅下滑,为缓解现金流压力,部分主权基金可能抛售黄金储备,增加市场实物供给。这属于一次性流动性事件,一旦封锁缓解或储备调整结束,抛压有望快速消退,并转为补库需求。

    美债收益率走高:美国10年期国债收益率已突破4.3%,最新徘徊在4.35%-4.39%区间,接近4.8%-5.0%下一阻力。高收益率提升持金机会成本,压制非孳息资产需求。

    然而,基本面并非一边倒利空:

    能源价格引发的通胀预期:中东冲突持续推高油价,市场已定价能源通胀冲击,这反而为黄金提供长期支撑(通胀对冲属性)。

    美国财政压力持续:联邦债务已达38.5万亿美元,债务/GDP比率122.5%,本财年赤字预计超2万亿美元。关税退税、军费开支、债务服务成本上升形成恶性循环,市场预期美联储可能被迫干预长端收益率(财政主导),届时实际收益率下降、美元走弱,将显著利好黄金。

    美元指数表现:DXY目前在99.3-99.4附近,虽有回升但尚未突破100.50关键阻力,若美元受阻回落,金价反弹动能将增强。

    地缘政治方面,美伊谈判信号反复(特朗普推迟打击但伊朗否认谈判),市场对冲突长期化仍有顾虑,避险需求时隐时现,但油价驱动的“更高更久”利率预期目前盖过了纯避险逻辑。

    技术面分析

    (现货黄金日线图 来源:易汇通)

    日线级别:金价已跌破4400-4500美元重要支撑带,直接考验200日均线(约4100美元)。昨日在低位出现明显下影线,显示多头在4000-4100美元区域积极防守。只要该支撑不破,整体多头趋势(均线仍向上排列)仍未被破坏,这是2024年以来最大一次回调。突破4600美元方能确认底部成立,进一步打开向5000美元反弹空间。

    4小时图:短期偏空,价格运行于下行通道内,位于50期和100期SMA下方,RSI(14)徘徊在39附近(低于50中轴),MACD虽有金叉但仍处于低位。当前反弹缺乏成交量配合,卖方仍占优势。

    关键技术位:

    支撑:4300美元 → 4098美元(年内低点)→ 4000美元(200日均线)
    阻力:4450-4500美元 → 4795美元(50日均线)→ 5000美元心理关口

    后市展望

    未来两周,预计金价将继续区间震荡。4000美元支撑若有效守住,叠加美元指数在99.4附近遇阻,可期待反弹测试4600美元;若美元指数突破100.50或收益率持续上行至4.8%以上,则可能进一步下探4000美元下方,进入更深整理。


    风险提示

    上行风险:美元指数回落、美伊冲突升级推高油价与通胀预期。

    下行风险:收益率持续突破4.8%、海湾抛售延长、美元指数站上100.50。

    突发事件:任何美伊谈判新进展或美联储官员讲话都可能引发剧烈波动。

    北京时间01:34,现货黄金报4386.05美元/盎司,跌幅0.47%。
