Wind Power Generators Type 3 and 4

 Wind Power Generators Type 3 and 4 Saat ini, ada dua jenis PLTB yang popular di dunia, yaitu type 3 dan type 4. Keduanya ada di Indonesia, yaitu Sulawesi Selatan. Pada PLTB type 3, digunakan generator induksi rotor belitan. Rotor motor induksi disuply dengan konverter arus terkendali yang frekuensinya menyesuaikan kebutuhan rotor melalui slip ring dan sikat. Frekuensi rotor diatur sedemikian rupa sehingga kecepatan sudut mekanik rotor ditambah kecepatan sudut arus rotor sama dengan kecepatan sinkronnya. Pada generator sinkron konvensional, kecepatan sudut arus rotor sama dengan nol (dc) sehingga kecepatan rotor harus sama dengan kecepatan sinkron. Dengan cara ini, kecepatan rotor generator bisa berubah-ubah sesuai dengan daya maksimum yang dikehendaki dengan tetap menjaga frekuensi statornya tetap. Rating dari konverter daya sebanding dengan variasi kecepatan rotor yang diijinkan. Biasanya, rating konverter yang diperlukan hanyalah 20% dari rating generatornya. Pada sistem ini, yang b

You should use forums rather than Slack/Discord to support developer community

 https://www.mooreds.com/wordpress/archives/3451   Hot take after a year or so of trying to build a developer community. If you can pick only one, use forum software rather than synchronous chat software for community building around a developer platform. While there are tradeoffs in terms of convenience and closeness, for most developer communities a public, managed forum is better than a private, unsearchable Slack. There are a few key differences between forum software (which includes packages like nodebb, forem, discourse, and others) and chat software (like Slack, Facebook groups, or Discord). First, though, it’s important to know what you are trying to accomplish. If you are trying to get immediate feedback from a small set of users, then synchronous solutions are better. You can be super responsive, your users will feel loved, and you’ll get feedback quickly. However, synchronous solutions go beyond chat and include phone and video calls. The general goal of valida
